Next, we observe that the graph is to the right of the endpoint. Using $x$ to represent the graph, we can express the inequality as $x$ is **greater than** $\text{-}4.$ Algebraically, it can be written as
$\begin{gathered}
x > \text{-}4.
\end{gathered}$

b

The graph is to the right of the endpoint, so it represents all values greater than or equal to $x=2.$ Thus, our inequality can be written with the $\geq$ symbol as $\begin{gathered} x\geq2. \end{gathered}$

c

First, we see that the circle at the endpoint is open. This means that $2$ is **not** included. Next, we observe that the graph lies to the left of the endpoint. Therefore, the inequality should be written as $x$ less than $2.$

$\begin{gathered}
x < 2 \end{gathered}$
