Answer:
The area under the function .
Step-by-step explanation:
We want to find the Riemann Sum for with 4 sub-intervals, using right endpoints.
A Riemann Sum is a method for approximating the total area underneath a curve on a graph, otherwise known as an integral.
The Right Riemann Sum is given by:
where
From the information given we know that a = 1, b = 3, n = 4.
Therefore,
We need to divide the interval [1, 3] into 4 sub-intervals of length :
Now, we just evaluate the function at the right endpoints:
Next, we use the Right Riemann Sum formula
