2-9.

For

, the estimation of *A*(*f*, 2 ≤*x*≤ 6) is shown below using four midpoint rectangles. Calculate*A*(*f*, 2 ≤*x*≤ 6) using these rectangles. How reasonable is your result? Homework Help ✎

*A* = (base)(height)

Base = 1 for all rectangles. Height is determined by the function, evaluated at midpoints.
