Horizontal stretch will exhibit similar properties on other functions. The only time a graph is horizontally stretched away from the y axis is when the graph stretches away from the axes. I have noticed this to be the case for all vertical stretches.

However, what you might have observed is how the y values remained the same. I was surprised to see that, as expected, the graph stretched by a factor of two to three by a factor of two to three. Let’s take a look at how f(x) = x2 will get affected by the values of 1/2 and 1/3. Can you explain what this means for functions such as f(x)? A scale factor of 1/a multiplied by x will stretch f(x)’s graph horizontally by a factor of a. In order to stretch a function horizontally, multiply the input values by the scaling factor, a, where 0 < 1/a < 1 are your input values. Now that we know the basics of horizontal stretching, let’s move onto exploring more about it when you’re ready. I have linked some articles on this page that may be helpful to you if you are in need of some refresher material. It is important to know how they work in the simplest terms possible.In particular, you should refresh your knowledge of vertical transformations and horizontal transformations.It is important in our study of Python to understand the different kinds of parent functions that we may encounter on our way.You should ensure that you have thoroughly reviewed your understanding of parent functions, translations, and vertical stretches if you would like to move on to the next section.

Additionally, we can learn how to plot as well as refine a new function more precisely and quickly based upon the scaling factors that we apply. Getting a sense of how graphs can be stretched horizontally will be useful if we are looking to graph a family of functions. If a chart is expanded vertically, it’s because the x-axis is raised and the y-axis is shifted.

Therefore, understanding how this technique works before applying it is a very important step. There are a number of techniques for writing functions graphs, but one of the most popular ones is horizontal stretching. This might be because they may have been stretched horizontally by extending their base function. In some cases the graphs appear similar, but they may have different widths – and this is something that you may have already experienced.
