Question

What is the rule for dilation? Like, for translation, you add/subtract the units being translated from the x and y value. what do you do for dilation??

Answer 1

Putting a coefficient other than 1 in front of the x or y term (before it is raised to any power) will expand or "squash" the plotted curve in either the x or y direction.

I have never heard this referred to as 'dilation', but I assume that is what they mean here.
