If x reprents a number then write an expression for 7 more than one half the number

the answer is 7+(x÷2) im pretty sure but i haven't done those in a while.

so what is the problem what are they asking you to solve

step-by-step explanation:

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
