B.
5x2 + 11

C.
5x2 + 1

D.
7x2 – 2x + 11

Step-by-step explanation:

(7x²+6)-(2x-5)

=7x²+6-2x+5

optionD

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
