I’m pretty sure the correct answer is c. but i’d like to double check.

4x + 1  → C

(f + g)(x) = f(x) + g(x) = 3x - 1 + x + 2 = 4x + 1

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
