Let f(x) = 4x2 + x + 1 and g(x) = x2 – 2. Find g(f(x)). Show each step of your work

Answer 1

4x^4-16x^2+x+17

Answer 2

i think so

Answer 3

steps

Answer 4

If you have to find g(f(x), all you have to do is substitute (f(x) in for x in g(x).

G(f(x))= (4x^2 +x +1)^2 -2

Now just simplify:

4x^2 + x^2 +2 - 2

And the 2's cancel so you end up with

4x^2 +x^2
