Given f(x)=x^3 and g(x)=4x+3, find g(f(3))

Question

Given f(x)=x^3 and g(x)=4x+3, find g(f(3))

a. g(f(3))=108

b. g(f(3))=3,375

c. g(f(3))=111

d. g(f(3))=405

Answer 1

First we would need to plug 3 into f(x). When we do this we get 27. Now we need to plug f(3) = 27 into g(x) so g(27) = 4(27)+3 = 111. So C would be the correct answer.
