Question

Given f(x)=2x-1 and g(x)=1/2f(x) describe the transformation from f(x) to g(x)

Answer 1

step 1: Horizontally shrink by 2 => f(x*1/2) = x-1

step 2: Shift up by 1/2 => f(x) = x-1/2

Explanation:

Assuming when you say 1/2*f(x) aka 0.5 * (2x-1) you first turn 2x into just x by horizontally shrinking it by 2.

Then you have to turn -1 into -1/2, for that you just add 1/2 aka shifting up 1/2.

If you ever forget the transformations, or how to use them here's a little cheat sheet :)
