Question

Help?!?!?please?!?!?

Answer 1

D

Explanation:

note that (f - g)(x) = f(x) - g(x)

f(x) - g(x)

= 4x - 3 - (x + 4)

= 4x - 3 - x - 4 ← collect like terms

= 3x - 7 → D

Answer 2

Answer: OPTION D

Explanation:

To solve the exercise shown in the image attached you must subtract the functions f(x) and g(x), as you can see below:

`(f-g)(x)=4x-3-(x+4)`

Distribute the negative sign and then you must add like terms. Therefore, you obtain:

`(f-g)(x)=4x-3-x-4\\(f-g)(x)=3x-7`
