Maximum and Minimum Turning Points

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.

(1)

(2)

From (1) and (2) we get a=2 and b=6.[/color]
