A
x + 4

B
x – 2

C
x

D
5x – 2

E
x – 4

Answer 1

the answer is D. let me know if you need an explaination

Answer 2

The correct option is A)
`(f-g)(x) = x +4`

Explanation:

We need to calculate (f-g)(x)

Given:-

`f(x) = 3x +2 \ \text{and} \ g(x) = 2x - 2`

Subtract g(x) from f(x)

`(f-g)(x) = 3x +2 -(2x - 2)`

`(f-g)(x) = 3x +2 -2x +2`

`(f-g)(x) = x +4`

Therefore, the correct option is A)
`(f-g)(x) = x +4`
