Question

F(x)=x^2 what is g(x)?
pls help me

Answer 1

C.

Explanation:

The transformation f(x) ---> a f(x) stretches the graph of f(x) vertically by a factor a.

The point (1, 1) on f(x) transforms to (1,9) on g(x).

This is a vertical transformation of factor 9, so g(x) = 9f(x)

= 9x^2 or (3x)^2.
