Hi!

What's the idea behind compressing functions when graphing, compressing horizontally or vertically:

1.

There is no amplitude, what's the function of the second2?

Consider the function -- if the constant A is introduced then the function will be stretched vertically by factor A, and the function will be squeezed horizontally by factor A. Here is an example where and A = 3. See how is streteched vertically while its period remains the same, and is squeezed horizontally while it's height remains the same?
