[tex] \large \boxed{(f - g)(x) = f(x) - g(x)}[/tex]
We subtract the f(x) by g(x) which means that we subtract 3x-1 from x+2.
[tex] \large{(f - g)(x) = (3x - 1) - (x + 2)}[/tex]
Cancel the parentheses by distributing the negative sign in x+2.
[tex] \large{(f - g)(x) = 3x - 1 - x - 2}[/tex]
Combine like terms.
[tex] \large{(f - g)(x) = 2x - 3}[/tex]
