Answer:
\begin{gathered} a)\text{ }\lbrace x\text{ \mid x }\ge\text{ 2\textbraceright} \\ b)\text{ \lbrack2, }\infty) \end{gathered}

See graph below

Step-by-step explanation:

Given:


x\text{ \ge 2}

To find:

to write in set builder notation, interval notation and graph the inequality

a) In set-builder notation:


\begin{gathered} \lbrace x\in\Re\text{ \mid x }\ge\text{ 2\textbraceright} \\ \lbrace x\text{\mid x }\ge\text{ 2\textbraceright} \end{gathered}

b) Interval notation:


\begin{gathered} [\text{ \rbrack represents inequality with an equal sign or that the number is inclusive} \\ (\text{ })\text{ shows that the number is not inclusive} \\ Notation:\text{ \lbrack2, }\infty) \end{gathered}

c) Graphing the inequality on a number line:

The circle is shaded because the inequality has an equal sign attached
