Explanation

**Given information:**

The curve function is

The region lies between

**Calculation:**

Draw the graph for the function

**Calculation:**

Find the width

Here, the upper limit is *b*, the lower limit is *a*, and the number of rectangles is *n*.

The expression to find the upper sum of areas of

Here, the maximum height of the first rectangle is *n*^{th} rectangle is

Find the upper sum of areas for two rectangles as shown below.

Substitute *b*, 0 for *a*, and 2 for *n* in Equation (1).

Refer to Figure (1).

The maximum values of the function occur at

Take the maximum height of the first rectangle’s

Substitute 2 for *n*, 3 for

Therefore, the upper sum of the function for two rectangles is

The expression to find the lower sum of areas of

Here, the minimum height of the first rectangle is *n*^{th} rectangle is

Find the lower sum of areas for two rectangles as shown below.

Refer to Figure (1).

The minimum values of the function occur at

Take the minimum height of the first rectangle’s

Substitute 2 for *n*, 2 for

Therefore, the lower sum of the function for two rectangles is

Draw the graph for the function

Find the upper sum of areas for four rectangles as shown below.

Substitute *b*, 0 for *a,* and 4 for *n* in Equation (1).

Refer to Figure (2).

Take the maximum height of the first rectangle’s

Substitute 4 for *n*, 2.7 for

Therefore, the upper sum of the function for four rectangles is
