Problem
Select the description that corresponds to the graphed function.
Step-by-step solution
The graph extends infinitely to the right, covering all positive x-values, and to the left, covering all negative x-values. The graph extends infinitely upwards and downwards, covering all real y-values. Therefore, the domain is all real numbers and the range is all real numbers.
Answer
The domain and range of the function are both the set of all real numbers.
