Answer
Interval notation :$\quad(-1,1]$
Inequality : $\quad \quad-1\lt x \leq 1$
Work Step by Step
Left parenthesis indicates that $-1$ is not part of the graph and
a right bracket indicates that $1$ is part of the graph.
Thusm the closed interval is $(-1,1]$.
It consists of all real numbers $x$ greatear than $-1$ but less than or equal to $1$.
Hence, the interval notation is $-1\lt x \leq 1$.
