Question

Find (f º g)(–2) if f(x) = 4x – 3 and g(x) = 3x + 3
Select one:
a. 10
b. –4
c. –15
d. 0

Answer 1

(f º g)(–2) is the same as f(g(-2))
That means you need to find g(-2) first.

Answer 2

Use function g(x) with x = -2.
What do you get for g(-2) ?

Answer 3

it's c, the solution of g(x) is -3 once you plug it in the other equation gives you -15
