13 should be b and
14 is a because geometric mean to have a common ratio
Using integration, it is found that the area under the graph of f(x) in the desired interval is of 1 unit squared.
<h3>How is the area under a graph found?</h3>
The area under the graph of a curve f(x) between x = a and x = b is given by the following integral:

In this problem, the function and the limits of integration are given by:


Hence:

Using substitution:



Hence:

Applying the Fundamental Theorem of Calculus:

Hence, the area under the graph of f(x) in the desired interval is of 1 unit squared.
