Answer

Interval notation : $\quad[0,3)$ Inequality : $\quad 0\leq x \lt 3$

Work Step by Step

Left bracket indicates that $0$ is part of the graph and right parenthesis indicates that $3$ is not part of the graph. Thus, the closed interval is $[0,3)$. It consists of all real numbers $x$ that are greater than or equal to $0$ but less than $3$. Hence, the interval notation is $0\leq x \lt 3$.
