You are given the table below.
x 4 8 12 16 20
f(x) 11 25 16 9 31
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.
20
(integral) f(x)dx
4

The integral value of is

Further explanation:

The equation of the line can be expressed as follows,

Given:
