Using M(3), we find that the approximate area of the shaded region below is
(A) 9
(B) 19
(C) 36
(D) 38
(E) 54
The graph of a continuous function f passes through the points (4,2), (6,6), (7,5), and (10,8).
Using trapezoids, we estimate that
(A) 25
(B) 30
(C) 32
(D) 33
(E) 41
The area of the shaded region in the figure is equal exactly to ln 3. If we approximate ln 3
using L(2) and R(2), which inequality follows?
