    Factor x out of 3x3−x. y=x(3x2−1)x2−4x Factor x out of x2−4x. y=x(3x2−1)x(x−4) Reduce the expression by cancelling the common factors. More Steps y=3x2−1x−4

    and since its a function technically it eventually will if thats what your meaning

    yeah... but it cant really cross the y axis though, right? becuase a functon will cross the y axis when x = 0 and if x = 0 then x^2 - 4x = 0 =0^2 - 4*0 = 0 so we're dividing by zero... yeah? so at that point, y = infinity
