To find the domain of the function , we need to identify the values of for which
the logarithmic function is defined.
For to be
defined, the argument of the logarithm, , must be positive
(since the logarithm is only defined for positive values of the argument).
To solve , we
first note that will be positive when the denominator is positive. Therefore, we need to find where .
Factor the expression:
We want to determine when the product is positive. To do this, we analyze the sign of in
the intervals determined by the critical points and .
For , both
