Values of the function g are shown in the table below. Use a trapezoid sum with the sub-intervals suggested by the table to estimate the area between g and the
x-axis on [0,10].
average the left-hand sum and right-hand sum
The sub-intervals are [0,1], [1,3], [3,6],[6,7],[7,8],[8,10]. Since they have unequal lengths, it's probably easiest to find the left-hand sum and right-hand sum, then take their average.
