    f^-1 (x) = (x+2) / 3

    Step-by-step explanation:

    To find the inverse of a function, exchange x and y and solve for y

    y = 3x-2

    Exchange x and y

    x = 3y-2

    Solve for y

    Add 2 to each side

    x+2=3y-2+2

    x+2 = 3y

    Divide each side by 3

    (x+2) / 3 = y

    The inverse of the function is

    f^-1 (x) = (x+2) / 3
