I was given the points (2, -1) and (10,-1) and also a max of 4. How would I go about finding the equation of the parabola given this info?
How do I find the equation of a parabola given the max, and two points?

0You should be able to deduce first that the vertex of your parabola is at $(6,4)$ (why?). You now have three points; substitute the appropriate values in $y=ax^2+bx+c$, and you now have three equations in three unknowns. – 2011-12-15
