Question

F(x) = 7x + 1 - 8

g(x) = -2
Find (f - g)(x).
A. (f-g)(x) = |7x - 5|
B. (f-g)(x) = 7x - 7+2
C. (f-g)(x) = |7x| - 5
D. (f-g)(x) = |7x+1-6

Answer 1

Answer: 7x-5

Explanation:

`(f-g)(x)=f(x)-g(x)=(7x+1-8)-(-2)=\boxed{7x-5}`

Answer 2

D. (f-g)(x) = |7x+1|-6

Explanation:

f(x) = |7x + 1| - 8

g(x) = -2

(f - g)(x) = f(x) - g(x) = |7x + 1| - 8 - (-2)

(f-g)(x) = |7x + 1| - 6
