find the domain and range of the function:

Explanation:

Step1: Identify domain from graph

The domain is the set of all x - values. Looking at the graph, the x - values range from - 7 to - 1. In interval notation, this is $[-7,-1]$.

Step2: Identify range from graph

The range is the set of all y - values. The y - values range from 0 to 3. In interval notation, this is $[0,3]$.

Answer:

Domain: $[-7,-1]$, Range: $[0,3]$
