This question is similar to one I posted yesterday. I have found d, but I'm unsure regarding the remaining values. Can anyone help? Many thanks. Q. The function has a max point at (0, 4) and a point of inflection at (1, 0). Find the values of a, b, c & d. Attempt: ...(when (x, y) = (0, 4) ...(when x = 0) ...(when x = 1, via point of inflection (1, 0)) Ans.: (From text book): a = 2, b = 6, c = 0, d = 4.

Correct up to your last line. a  3a + 4 = 0, 2a = 4, a = 2.
