    These are linear equations, remember y = mx + b g(f(x)) = (5x − 3) + 4 = 5x +1 f((g(x)) = 5(x + 4) − 3 = 5x + 17

    the only thing that differs between them is the y-intercept

    Which of the following expressions is the inverse of the function y equals quantity x minus 2 divided by 3? y = 3x + 2 y = 2x + 3 y equals quantity x minus 3 divided by 2 y equals quantity x plus 2 divided by 3

    First write out the equation, then to find the inverse set y to x and x to y then solve for y

    now replace y with x and x with y and solve for y and you have the inverse of that function

    If you had y = x + 2 to find the inverse x = y + 2 solve for y y = x - 2
