Solve the equation with the replacement set {–43, –7, 7, 43} equation = |25 – x| = 18 choice of answers a. –7, 7 b. 7, 43 c. 7 d. 43

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
