Question 167811: Need help graphing this equation. Find the dimensions of the rectangular field of maximum area which can be enclosed with 400 feet of fence.
The vertex is (100, 10000), -w^2+200w and the parabola would be downward, but when I put the equation in my calulator. I do not see the parabola.

You can put this solution on YOUR website!
You have found the turning point which will give the maximum area correctly.
I would suspect that your calculator is not set to show such a wide range of x and y. Make sure that it will display x up to 200 and the y value up to 10000. The graph should then display.
