oh. I'll examine tomorrow. bye.
Last equation was the derivative after being simplified.
Okay, I get the product rule.
The derivative of...
would use the product rule.
I don't know how to use th math script..
Well I cheated after that and plotted the points with a tiny BASIC program.
Wow thats really ingenious. Thats cool.
Ah, I see now. Guess no calculus is needed.
Add 2 to both sides to solve for Yintercept.
Multiply both sides of equation by Xintercept so as to
solve for the area; you can divide by 2, if you want to

I think what he may have done is made a triangle by drawing a line from the origin to the point and making a right triangle.
John, I'm curious how you came up with that. Think you could show more work? I can't seem to find where that equation is coming from.
Slope = -2
Thank you both for helping.
The x intercept must be greater than one.
I arrived at this by drawing a picture and setting two
similar triangles proportions equal.
Sorry explanation so poor.
Start with the basics.
