I have a problem of which I do not know where to start or how to go about solving it.

- The graph of the function equation y=f(x) is shown, where f(x) is a cubic polynomial. The graph cuts through the origin, touches the x-axis at (3,0) and passes through (4,4).

a) - Prove that f(x) = x

^{3}-6x

^{2}+9x

b) - Use calculus to find the coordinates of the local maximum of the graphAny help would be appreciated. Thanks in advance (:
