Answer
Interval notation : $\quad[2,\infty)$
Inequality : $\quad x\geq 2 $
Work Step by Step
Left bracket indicates that $2$ is part of the graph.
The shaded region is to the right of $2$ thus, the half open interval is $[2,\infty)$.
It consists of all real numbers $x$ that are greater than or equal to $2$.
Hence, the interval notation is $x\geq 2 $.
