Step 1 : Let g (x) be a function which represents f (x) after the vertical compression by a factor of 2. When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original. Create a table for the function [latex]g\left(x\right)=\frac{3}{4}f\left(x\right)[/latex]. If the constant is between 0 and 1, we get a horizontal stretch; if the constant is greater than 1, we get a horizontal compression of the function. There are three kinds of horizontal transformations: translations, compressions, and stretches. In this graph, it appears that [latex]g\left(2\right)=2[/latex]. [latex]g\left(x\right)=\frac{1}{4}f\left(x\right)=\frac{1}{4}{x}^{3}[/latex]. We use cookies to ensure that we give you the best experience on our website. An important consequence of this is that horizontally compressing a graph does not change the minimum or maximum y-value of the graph. To determine a mathematic equation, one would need to first identify the problem or question that they are trying to solve. These lessons with videos and examples help Pre-Calculus students learn about horizontal and vertical These occur when b is replaced by any real number. Observe also how the period repeats more frequently. $\,y = f(3x)\,$! Graph of the transformation g(x)=0.5cos(x). Figure %: The sine curve is stretched vertically when multiplied by a coefficient. No matter what math problem you're trying to solve, there are some basic steps you can follow to figure it out. Other important from y y -axis. 100% recommend. This video provides two examples of how to express a horizontal stretch or compression using function notation. In the case of above, the period of the function is . a function whose graph is unchanged by combined horizontal and vertical reflection, \displaystyle f\left (x\right)=-f\left (-x\right), f (x) = f (x), and is symmetric about the origin. To determine what the math problem is, you will need to take a close look at the information given and use your problem-solving skills. $\,3x\,$ in an equation But, try thinking about it this way. Do a vertical stretch; the $\,y$-values on the graph should be multiplied by $\,2\,$. Learn about horizontal compression and stretch. If you're struggling to clear up a math equation, try breaking it down into smaller, more manageable pieces. Transform the function by 2 in x-direction stretch : Replace every x by Stretched function Simplify the new function: : | Extract from the fraction | Solve with the power laws : equals | Extract from the fraction And if I want to move another function? to Given a function [latex]y=f\left(x\right)[/latex], the form [latex]y=f\left(bx\right)[/latex] results in a horizontal stretch or compression. If you're looking for academic help, our expert tutors can assist you with everything from homework to test prep. Then, [latex]g\left(4\right)=\frac{1}{2}\cdot{f}(4) =\frac{1}{2}\cdot\left(3\right)=\frac{3}{2}[/latex]. The input values, [latex]t[/latex], stay the same while the output values are twice as large as before. I can help you clear up any math tasks you may have. if k > 1, the graph of y = f (kx) is the graph of f (x) horizontally shrunk (or compressed) by dividing each of its x-coordinates by k. Because the x-value is being multiplied by a number larger than 1, a smaller x-value must be input in order to obtain the same y-value from the original function. Both can be applied to either the horizontal (typically x-axis) or vertical (typically y-axis) components of a function. Horizontal stretch/compression The graph of f(cx) is the graph of f compressed horizontally by a factor of c if c > 1. You can see that for the original function where x = 0, there's some value of y that's greater than 0. In this case, multiplying the x-value by a constant whose value is between 0 and 1 means that the transformed graph will require values of x larger than the original graph in order to obtain the same y-value. 2 If 0 < a< 1 0 < a < 1, then the graph will be compressed. Copyright 2005, 2022 - OnlineMathLearning.com. Math can be difficult, but with a little practice, it can be easy! Vertical Stretches and Compressions. Each change has a specific effect that can be seen graphically. If you have a question, we have the answer! Vertical Stretches and Compressions . This type of Points on the graph of $\,y=f(3x)\,$ are of the form $\,\bigl(x,f(3x)\bigr)\,$. If the graph is horizontally stretched, it will require larger x-values to map to the same y-values as the original function. y = c f(x), vertical stretch, factor of c, y = (1/c)f(x), compress vertically, factor of c, y = f(cx), compress horizontally, factor of c, y = f(x/c), stretch horizontally, factor of c. Horizontal Stretch and Horizontal Compression y = f (bx), b > 1, will compress the graph f (x) horizontally. This means that most people who have used this product are very satisfied with it. Mathematics. Ryan Guenthner holds a BA in physics and has studied chemistry and biology in depth as well. If [latex]a>1[/latex], then the graph will be stretched. This video discusses the horizontal stretching and compressing of graphs. When , the horizontal shift is described as: . With a little effort, anyone can learn to solve mathematical problems. Graph Functions Using Compressions and Stretches. Video quote: By a factor of a notice if we look at y equals f of X here in blue y equals 2 times f of X is a vertical stretch and if we graph y equals 0.5 times f of X.We have a vertical compression. This is a transformation involving $\,y\,$; it is intuitive. Multiply the previous $\,y\,$-values by $\,k\,$, giving the new equation Replace every $\,x\,$ by $\,k\,x\,$ to Look at the value of the function where x = 0. Hence, we have the g (x) graph just by transforming its parent function, y = sin x. Here is the thought process you should use when you are given the graph of $\,y=f(x)\,$.

In general, a horizontal stretch is given by the equation y=f(cx) y = f ( c x ) . The graph of [latex]y={\left(0.5x\right)}^{2}[/latex] is a horizontal stretch of the graph of the function [latex]y={x}^{2}[/latex] by a factor of 2. Suppose a scientist is comparing a population of fruit flies to a population that progresses through its lifespan twice as fast as the original population. $\,y\,$ A function [latex]f[/latex] is given in the table below. In math terms, you can stretch or compress a function horizontally by multiplying x by some number before any other operations. horizontal stretch; x x -values are doubled; points get farther away. Because each input value has been doubled, the result is that the function [latex]g\left(x\right)[/latex] has been stretched horizontally by a factor of 2. problem solver below to practice various math topics. $\,y = 3f(x)\,$, the $\,3\,$ is on the outside; When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function. *It's the opposite sign because it's in the brackets. Horizontal Stretch The graph of f(12x) f ( 1 2 x ) is stretched horizontally by a factor of 2 compared to the graph of f(x). Doing homework can help you learn and understand the material covered in class. A horizontal compression (or shrinking) is the squeezing of the graph toward the y-axis. Replacing every $\,x\,$ by $\,\frac{x}{3}\,$ in the equation causes the $\,x$-values on the graph to be multiplied by $\,3\,$. shown in Figure259, and Figure260. In other words, this new population, [latex]R[/latex], will progress in 1 hour the same amount as the original population does in 2 hours, and in 2 hours, it will progress as much as the original population does in 4 hours. A General Note: Vertical Stretches and Compressions. This video talks about reflections around the X axis and Y axis. The $\,y$-values are being multiplied by a number between $\,0\,$ and $\,1\,$, so they move closer to the $\,x$-axis. The following table gives a summary of the Transformation Rules for Graphs. Given a function f (x) f ( x), a new function g(x) = af (x) g ( x) = a f ( x), where a a is a constant, is a vertical stretch or vertical compression of the function f (x) f ( x).
