Question

what is the range of the graph? options: -7 ≤ x < 5, -3 ≤ x < 1, -7 ≤ y < 5, -3 ≤ y < 1

Explanation:

Step1: Define range of a graph

Range is the set of all valid $y$-values of the function.

Step2: Identify $y$-values from the graph

The closed dot is at $y=-3$ (included), open dot at $y=1$ (not included). All $y$-values lie between them.

Answer:

D. $-3 \leq y < 1$
