How do you do this question? Would you calculate or look at the graphs or neither?

L ≤ T ≤ I ≤ M ≤ R

Step-by-step explanation:

Looking at the graph is important.  The function is increasing and concave down on the interval.

Left rule will give us the smallest approximation, and right rule will give us the largest approximation.

Trapezoidal rule will under-approximate the area, and midpoint rule will over-approximate the area.

the correct is answer is a 9-sided polygon!
