Question

F(x) = x^2. What is g(x)?
g(x)

Answer 1

B

Explanation:

To find g(x), I suggest first simplifying some of the answers so they are easier to visualize.

A; stays the same (3x^2)

B: (3x)^2=9x^2

C: (9x)^2=81x^2

D: (1/3x)^2=1/9x^2

After doing this, it is easy to see that the answer is B because when plugging in 1 for the x-value, you get 9 as the y-value.
