Interval Notation: $(-1 , 1]$ Inequality Form: $-1 \lt x \le 1$
The graph involves an open parenthesis and a close bracket. This means that the number where the bracket is located (1) is included in the interval while the number where the parenthesis is located (-1) is not included in the interval. The graph covers $x$ from $-1$ to $1$. This means that the interval is $(-1 , 1]$. The inequality equivalent of this is $-1 \lt x \le 1$.
