Question

1. domain: () () range: () () 10.

Explanation:

Step1: Identify domain concept

The domain is the set of all x - values for which the function is defined. Looking at the graph, as the graph extends infinitely to the left and right along the x - axis, the x - values can be any real number.

Step2: Identify range concept

The range is the set of all y - values for which the function is defined. From the graph, the y - values also extend infinitely in both the positive and negative directions.

Answer:

Domain: $(-\infty,\infty)$
Range: $(-\infty,\infty)$
