Question

question express the interval using two different representations. -6,9 answer attempt 1 out of 2 inequality notation: number line:

Explanation:

Step1: Recall interval - notation to inequality - notation rule

The closed - interval $[a,b]$ means $a\leq x\leq b$. Here $a=-6$ and $b = 9$.

Step2: Write the inequality notation

The inequality notation for the interval $[-6,9]$ is $-6\leq x\leq9$.

Answer:

Inequality Notation: $-6\leq x\leq9$
Number Line: Mark a closed - circle at $x=-6$ and a closed - circle at $x = 9$, and shade the region between them on the number line.
