Question

determine the range of the following graph:

Explanation:

Step1: Identify lowest y-value

The graph's minimum y-value is $-2$.

Step2: Identify highest y-value

The graph's maximum y-value is $7$.

Step3: Check endpoint inclusion

Open circles mean endpoints $y=5$ and $y=0$ are excluded, but all values between $-2$ and $7$ are covered.

Answer:

$-2 \leq y \leq 7$ (or in interval notation: $[-2, 7]$)
