3x2 - kx + 4 The graph of the function f(x) = will have a point of discontinuity if k is 3x2- 2x (2x +5) (x -3) For the function f(x) = (x - 3)(-2x + 1)' the vertical and horizontal asymptotes are Select one: O a. x = 2, y =1 O b. x = =,y=-1 0 0 x = - 7.y=-1 Od. x = -1, y = = The graph ( (x - a)(x-b)
