Vertical Shift Graph & Examples | How to Shift a Graph, Domain & Range of Composite Functions | Overview & Examples. To visualize a horizontal compression, imagine that you push the graph of the function toward the y axis from both the left and the right hand side. give the new equation $\,y=f(\frac{x}{k})\,$. Vertical compression means the function is squished down vertically, so its shorter. Additionally, we will explore horizontal compressions . $\,y = f(3x)\,$, the $\,3\,$ is on the inside; Even though I am able to identify shifts in the exercise below, 1) I still don't understand the difference between reflections over x and y axes in terms of how they are written. This seems really weird and counterintuitive, because stretching makes things bigger, so why would you multiply x by a fraction to horizontally stretch the function? Parent Functions And Their Graphs Meanwhile, for horizontal stretch and compression, multiply the input value, x, by a scale factor of a. Again, the minimum and maximum y-values of the original function are preserved in the transformed function. Review Laws of Exponents Horizontal and Vertical Stretching/Shrinking If the constant is greater than 1, we get a vertical stretch if the constant is between 0 and 1, we get a vertical compression. 221 in Text The values of fx are in the table, see the text for the graph. 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. If a1 , then the graph will be stretched. A General Note: Vertical Stretches and Compressions 1 If a &gt; 1 a &gt; 1, then the graph will be stretched.
