Question

You are given the table below.
Use the table and n = 4 to estimate the following. Because the data is not monotone (only increasing or only decreasing), you should sketch a possible graph and draw the rectangles.
The integral is from 2 to 10 of f(x).
Find the upper and lower estimates.

Answer 1

\[\int\limits_{2}^{10}f(x)dx\]

Answer 2

add the first 4, and add the last 4

Answer 3

im forgetting something

Answer 4

multiply each value by (10-2)/4 = 2

Answer 5

then do the adding
