Answer: OPTION D
Step-by-step 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:
[tex](f-g)(x)=4x-3-(x+4)[/tex]
Distribute the negative sign and then you must add like terms. Therefore, you obtain:
[tex](f-g)(x)=4x-3-x-4\\(f-g)(x)=3x-7[/tex]
