Question

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

Answer 1

At g(f(x)) , where it is x , we replace it with the whole f(x) :

Answer 2

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

Answer 3

Would (4x^2)^2 be 4x^4?

Answer 4

no the exponent applies to everything in the parenthesis
