Answer:

[tex](f-g)(x)=2x-3[/tex]

Step-by-step explanation:

The correct question is

If f(x)=3x-1 and g(x)=x+2, find (f-g)(x)

we know that

(f-g)(x) is equal to subtract the function g(x) from the function f(x)

so

[tex](f-g)(x)=f(x)-g(x)[/tex]

substitute the given functions

[tex](f-g)(x)=(3x-1)-(x+2)[/tex]

Remove the parenthesis

[tex](f-g)(x)=3x-1-x-2)[/tex]

Combine like terms

[tex](f-g)(x)=2x-3[/tex]
