Trapezoid Sum Exercises

Example 1

Let . Use a trapezoid sum with 3 sub-intervals to estimate the area between f and the x-axis on [0, 9]. Is this an overestimate or underestimate?

Example 2

The table below shows partial values of the function f(x). Use a trapezoid sum with 4 sub-intervals to estimate the area between the graph of f and the x-axis on [0, 1].
