WHICH IS BETTER? Part Three
Below is a comparison of using a different number of rectangles to approximate the same area under a curve for f(x). Decide which will best approximate A(f, a ≤ x ≤ b). Explain why.
If, in each situation, the rectangles all had equal widths, write expressions to find the area under the curve. Homework Help ✎
Look at the shaded area beneath each curve. Which sketch most accurately represents the actual area under the curve?
