Question:

Solve f(g(x) where x = 3 f(x) = 2x + 3 g(x) = 3(x+2)

Viviane C.
Answer:

It is important to first identify where the g(x) needs to be substituted in the f(x) equation. In this case f(x) = 2(g(x)) + 3 Thus, f(x) = 2(3(x+2)) + 3 Then, with x = 3 you plug it into the equation and solve for f(x). f(x) = 2(3(3) + 6) + 3 (Remember to apply the rule of distribution) f(x) = 2(9 + 6) + 3 f(x) = 30+3 f(x) = 33
