Question

Estimate the area under the curve f(x) = x2 + 1 from x = 0 to x = 6 by using three circumscribed (over the curve) rectangles. Answer to the nearest integer.

a. I assume under the curve means from f(x)=0 to the curve, and I assume circumstribed means right hand rectangle corner on the curve.

area= (x^2+1)at x=2,4,6
area=5+17+37
I'm intrigued how you got all those odd values for the areas when the width of each rectangle is 2 ....

Steve you plug the x value into the y formula which causes you to add 1 to the even value... always check your work.
