Cynthia began to draw midpoint rectangles to approximate A(f, −2 ≤ x ≤ 4) for
. Trace Cynthia's graph and finish drawing the remaining four midpoint rectangles. Then, compute the estimated area. Homework Help ✎
Make the remaining rectangles. Then calculate the areas of each rectangle and add them together to find A(f, −2 ≤ x ≤ 4).
The width of all of the rectangles is 1.
