Please help me determine the y-value at the maximum regarding this parabola. I tried solving it 2 times! The shape of the parabola is open down so has a maximum at it’s summit. The math question gave a table and data. I figured out the zeros and axis of symmetry. Here is the necessary information: 
 
First Zero: 
(0,0)
x1 = 0
 
Second Zero:
(80,0)
x2 = 80
 
Equation of the axis of symmetry: 
 
x1 + x2 / 2
 
= 0 + 80 / 2
 
= 80 / 2
 
= 40
 
Thanks!

This is more appropriate for http://math.stackexchange.com/ - this is for the math *software* Sage.
