Question

Use the function to evaluate the indicated expressions and simplify.
f(x) = 7x - 4
f(x2) = ____
(f(x))^2 = ____

Answer 1

What'd you get for an answer on this one?

Answer 2

i didnt

Answer 3

im not sure how to write the equation with f(x) stuff

Answer 4

Ok, well for the first one, in the expression for f(x) replace the x with an x^2.

For the second one, you are squaring the whole expression because f(x) is 7x-4 so f(x) squared is (7x-4)^2
