y = -0.002x^2 + 0.879x + 3.981

I know it gets hit at approx. 4 feet high. The -a gives the right shape like a hill. There's a -4.48 and 443.95 zero, which can be hit for distance. The max is (219.75, 100) so that seems doable. What am i missing?

**** i have to explain why it's not a good example. Another problem had an initial height that was negative and another problem had a vertex y value that couldn't possibly be hit. So what am I missing that makes this equation a poor model of a hitting siutation?
