Jonathan - Section 9-7 should be useful to you in finding the equation for your parabola. You should find out the distance between the two sides of the parabola at ground level, as well as the height at the highest point. For your graph, I suggest making the ground your x-axis, and the height your y-axis. Then you can use Excel to find an equation with quadratic regression. You might also find an equation for your parabola online. Good luck!
