Question

which graph represents the compound inequality? -3 < n < 1

Explanation:

Step1: Understand inequality notation

The compound inequality $- 3 < n<1$ means $n$ is greater than - 3 and less than 1. Open - circle is used for $<$ or $>$, and closed - circle for $\leq$ or $\geq$.

Step2: Analyze the graph

We need an open - circle at $n=-3$ and an open - circle at $n = 1$, and the line segment between them on the number line.

Answer:

The fourth graph (the one with open - circles at - 3 and 1 and the line segment between them on the number line)
