Question

Given that f(x)= 2x+1 and g(x)=3x-1/2 solve for g(f
(3))?

Answer 1

Substitute the value of f(x) into the place of x in the g(x) equation. You get g(x) = 3(2x+1) - 1/2. That simplifies to 6x + 3 - 1/2, or 6x + 2.5.

If you meant to have the 3x-1 in parentheses, the answer would be (3(2x+1)-1)/2. which equals (6x + 2)/2, giving you a final answer of 3x + 1.
