Question

Given that (3,-1) is on the graph of f(x), find the corresponding point for the function f(3x)

Answer 1

Answer:

  (1, -1)

Step-by-step explanation:

You have the point ...

  (3, f(3)) = (3, -1)

The corresponding point on the horizontally compressed graph will be ...

  (3x, f(3x)) = (3, -1)

  (x, f(3x)) = (1, -1) . . . . . the first coordinate of the given point is divided by 3
