**Graham**, Sunday, September 1, 2013 at 2:57am(a) Take the derivative and solve for x when y' is 0. Evaluate y at that value.

(b) Solve the equation for x when y is 0.

Alternatively, note that a ballistic curve of that form (quadratic) is symmetric around the maxima/minima and use the solution of one to solve the other.
