practice The function f is continuous on the interval [2, 8] and has values that are given in the table. ( F(x) dx ? using the subintervals [2, 5], [5, 7] and [7, 8], what is the trapezoidal approximation of X N . OO (x) m 2. The following table shows the speedometer readings of a truck, taken at ten minute intervals during one hour of the trip. Use the table and the midpoint rule to estimate the distance that the truck traveled in the hour. Watch your units! Time (min) O 20 Speed (km/h) 40
