b) What is the footballs' height at that distance.

Why not use ^ for powers like so: -.025x^2

Instead of writing out the word 'squared'?

After all, that is what SHIFT 6 is for.

From the graph, I made the assumption it is thrown from ground level. That may not be the case. It is probably thrown from a height of 5 feet at (0,5).
