Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 10.0 points The graph of a function f on the interval [0 , 10] is shown in 2 4 6 8 10 2 4 6 8 Estimate the area under the graph of f by dividing [0 , 10] into 10 equal subintervals and using right endpoints as sample points. 1. area ≈ 52 2. area ≈ 50 correct 3. area ≈ 53 4. area ≈ 51 5. area ≈ 54 Explanation: With 10 equal subintervals and right end points as sample points, area ≈ braceleftBig f (1) + f (2) + . . . f (10) bracerightBig 1 , since x i = i . Consequently, area ≈ 50 , reading off the values of f (1) , f (2) , . . . , f (10) from the graph of f . 002 10.0 points Cyclist Joe brakes as he approaches a stop sign. His velocity graph over a 5 second period (in units of feet/sec) is shown in 1 2 3 4 5 4 8 12 16 20 Compute best possible upper and lower es timates for the distance he travels over this period by dividing [0 , 5] into 5 equal subinter vals and using endpoint sample points.vals and using endpoint sample points....
