Question

1. domain: ( , ) range: ( , )

Explanation:

Step1: Identify domain

The domain is the set of all possible x - values. Looking at the graph, the left - most x - value is the smallest value in the domain and the right - most x - value is the largest. The graph extends from x=-4 to x = 4. So the domain is [-4,4].

Step2: Identify range

The range is the set of all possible y - values. The lowest y - value is at y=-2 and the highest y - value is at y = 2. So the range is [-2,2].

Answer:

Domain: [-4,4]
Range: [-2,2]
