Plot the new points to get the dilated shape. Explore this lesson to learn the definitions of dilation, scale factor, and center of dilation. Use our step-by-step calculator and example problems to learn how to perform dilations on a graph.
Dec 21, 2020 · Horizontal dilation. If x is replaced by x / A in a formula and A > 1, then the effect on the graph is to expand it by a factor of A in the x-direction (away from the y-axis). If A is between 0 and 1 then the effect on the graph is to contract by a factor of 1 / A (towards the y -axis).
Step 1: Identifying the Center of Dilation. Step 2: Finding the Scale Factor. Step 3: Multiply the Coordinates by The Scale Factor. Step 4: Graph the Dilated Figure. Step 5: Checking Your Answers. Wrapping Up. Understanding the Basics of Dilations.
Dilations are a way to stretch or shrink shapes around a point called the center of dilation. The amount we stretch or shrink is called the scale factor. If the scale factor is greater than 1, the shape stretches. If it's between 0 and 1, the shape shrinks. Questions.

- What's the correct order? Do you across and then down or the opposite?It actually doesn't matter! The key thing is that the dilation value affects the distance between two points. As in the first example (dilation by...
- How would you do it if there is no coordinate plane?That's a great question! While a coordinate plane is helpful in making our measurements more exact and accurate, it is by no means necessary. In fa...
- is this enlargement ? and what is a shearNo, unless you’re dilating shapes by a factor that is greater than 1. According to Wikipedia, a shear is “the component of stress coplanar with a m...

- How do you determine the direction of the dilation?If the point that you are dilating is directly above the point of dilation and you are dilating by 3, you take the distance from the point of dilat...
- What does that apostrophe at the end of "a"supposed to mean?It is called "prime", it's there to say that the point is not the original point, but the image of the original one after transformation. A = origi...
- why would you go 6 down and 3 to the right? (2:35)?To get from the point of origin to A. Then divide those by 3 and you have A'. Do you think you can figure out where A' might be? Hope this helps. G...
Jun 24, 2010 · Doing so “dilates” the graph, causing all points to move away from the axis to a multiple of their original distance from the axis. As an example of this, consider the following graph: Vertical Dilation (no Translation) The graph above shows a function before and after a vertical dilation.
The transformations of functions define how to graph a function is moving and how its shape is being changed. There are basically three types of function transformations: translation, dilation, and reflection.
Sep 7, 2018 · A dilation is a stretching or shrinking about an axis caused by multiplication or division. You can think of a dilation as the result of drawing a graph on rubberized paper, stapling an axis in place, then either stretching the graph away from the axis in both directions, or squeezing it towards the axis from both sides.
