Question

If f(x) = x + 2 and g(x) = 3x + 4, then f(g(x)) = ? A) 3x + 6 B) 3x + 10 C) 3x2 + 6x + 4 D) 3x2 + 10x + 6

Answer 1

A. 3x+6

Explanation:

To answer this problem you would want to replace the g(x) equation with for the x in the f equation and solve/simplify.

f(x)=x+2, g(x)=3x+4

(3x+4)+2

3x+6
