Question

Given f(x) = x^3 - 9x and g(x) = x^2, choose
the expression for (fºg)(x).

Answer 1

Answer and Step-by-step explanation:

We are given two functions, f and g. We are asked to find the value of f evaluated at g(x).

Here, we need to plug in every value of x in f(x) with the value of g(x).

f(g(x)) = $(x^2)^3-9(x^2)$

An exponent raised by an exponent results in the exponents multiplying together.

f(g(x)) = $x^6 - 9x^2$   <- This is the final answer.

I hope this helps!
