Question

Function f is shown on the graph below where two points are marked. If function f is horizontally compressed by a factor of 2, plot the two corresponding points that would lie on the transformed function.

Answer 1

If you have

`f(x) = x^2`

The point (2,4) would be transformed to (1,1)

Explanation:

If your compression is horizontal then the transformation you are making is the following

`g(x) = f(x/2)`

Therefore, if you have

`f(x) = x^2`

The point (2,4) would be transformed to (1,1)
