the variable w should appear in the function). it should be a quadratic function

Okay, so you have 682 feet of fencing to make up two "width sides" and one "length side" this translates to the equation: 682 = 2W + L You know from basic geometry that the area of a rectangle is length times width: A = L*W What you need to do is solve the first equation for L in terms of W: 682 = 2W + L L = 682 2W Then substitute that L value into the second function so that you have A in terms of just W: A = L*W A = (682 2W)W

go to where it says x min and type 100 go to where it says x max and type 200 go to where it says y min and type 80 go to where it says y max and type 60000 and see if it looks viewable

your approximation doesn't have to be mine but both of ours should be pretty close to the same thing is yours close to my?

k now you remember the file i gave you right? that vertex of the parabola i found by putting the parabola in vertex form gave me the exact (max width,max area)
