If put into a Texas-Instrument graphing calculator, you can use the "2nd trace" maximum button to find the maximum height. Adjust the window to see the top of the parabola. In the 2nd trace menu select option number 4. When prompted for the left bound move left of the vertex, when prompted for the right bound,move right of the vertex. When asked to guess, press enter and the y value is the answer, which is 64
