    Find the inverse of f(x) = -4x - 12
    f-1(x) = 4x - 3
    f-1(x) = -1/4x - 3
    f-1(x) = 1/4x + 3
    f-1(x) = -4x - 3

    Find the inverse of
    f(x) = 1/4x - 7
    f-1(x) = 4x + 7
    f-1(x) = -4x + 28
    f-1(x) = -4x - 7
    f-1(x) = 4x + 28

    Find the inverse of
    f(x) = -3x + 3
    f-1(x) = -3x + 1
    f-1(x) = -1/3x + 1
    f-1(x) = -1/3x - 1
    f-1(x) = 1/3x + 1
