Question

Find (g • f) ^(3) PLEASE HELLPP

Answer 1

The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=$g(f(x))=g(3x-2)=(3x-2)^2=9x^2-12x+4$

Now, we can evaluate (g°f) at 3:
$g(f(3))=9(3)^2-12(3)+4$
$g(f(3))=9(9)-36+4$
$g(f(3))=81-32$
$g(f(3))=49$

We can conclude that the correct answer is c. 49
