    (f - g) (x) = x - 3

    Step-by-step explanation:

    (f - g) (x) = f (x) - g (x)

    This means that you have to subtract the two equation.

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

    Then

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

    = 3x - 2 - 2x - 1

    = x - 3

    ∴ (f - g) (x) = x - 3
