    f(x) = -4x -2 f(-3) = -4(-3) -2 = .................. see we have just simply substituted x=-3 into the equation given?

    ok this is our equation f(x) = -4x -2 it's the same as saying y = -4x -2 and we want to substitute x=-3 into the equation, so we simply replace the x in the above equation by -3 y=-4(-3) -2 y= ? (you can do this)
