Explanation:

Step1: Identify lowest y-value

The minimum y-value on the graph is $-2$.

Step2: Identify highest y-value

The maximum y-value on the graph is $4$.

Step3: Define the range

The range includes all y-values between the minimum and maximum, inclusive, since the endpoints are filled dots.

Answer:

$-2 \leq y \leq 4$ (or in interval notation: $[-2, 4]$)
