If f(x)=5x-2 and g(x)=2x+1 , find (f-g)(x)

Answer:
The correct option is B.
Step-by-step explanation:
The given functions are
[tex]f(x)=5x-2[/tex]
[tex]g(x)=2x+1[/tex]
We have to ind the value of (f-g)(x).
[tex](f-g)(x)=f(x)-g(x)[/tex]
[tex](f-g)(x)=5x-2-(2x+1)[/tex]
[tex](f-g)(x)=5x-2-2x-1[/tex]
Combine like terms.
[tex](f-g)(x)=(5x-2x)-2-1[/tex]
[tex](f-g)(x)=3x-3[/tex]
Therefore option B is correct.
