Suppose we want to find the area under the function f(x) = 2x on the interval 1 ≤ x ≤ 3. Homework Help ✎
Sketch a graph of the curve shading the area of the region you are to find.
If left-endpoint rectangles are used will the estimate be too low or too high. Justify your answer.
If you used right-endpoint rectangles to estimate the area, will that estimate be too low or too high. Justify your answer.
Use your program to find an estimate using 20 left- and right-endpoint rectangles.
Too low, as rectangles will be under the curve.
Too high, as rectangles will be above the curve.
Left = 8.360, Right = 8.960
