I have a rectangle inscribed in the parabola defined by with one edge on the x-axis ? Would I assume that edge on the x-axis is x or 2x?

Your width is 2x, your height is y.
So area = b*h and differentiate Solve for 0 which one I use? positive or negative
So i'm guessing you're trying to maximize your area? Seeing as we can't have negative dimensions, we use +.
Thanks man it just seems I keep getting all sorts of things confused I get the dimsenions are
Looks good to me. Just remember, technically, our base is 2x, not x.
