Answer:

Both the domain and range are all real numbers.

Explanation:

The arrowheads at both sides of the graph show that values in x extend to the left forever and also extend to the right forever. That makes the domain all real numbers.

The same is true of values in y. They extend up and down forever. That makes the range all real numbers.
