Exercise 21 Page 526

Division by zero is not defined. This means that the denominator cannot be zero.

Graph:

Domain: All real numbers except
Range: All real numbers except

Practice makes perfect

To graph the given rational function, we will find its domain, asymptotes, and intercepts. We will find points using a table of values. Then, we will plot and connect those points. Finally, we will find the range of the function.

Domain

Consider the given function.
Recall that division by zero is not defined. Therefore, the rational function is undefined where
This means that is not included in the domain.
