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 $0\leq x \lt 3$.
