See the full explanation below.

We have to plot the graphs out of the functions with the help of the points individually for $f\left( x \right)$ and $g\left( x \right)$. The coordinates of $f\left( x \right)$ for $x=-2$ to $x=2$ are as follows: $\begin{align} & x=-2 \\ & f\left( x \right)=3 \end{align}$ $\begin{align} & x=-1 \\ & f\left( x \right)=3 \end{align}$ $\begin{align} & x=0 \\ & f\left( x \right)=3 \end{align}$ $\begin{align} & x=1 \\ & f\left( x \right)=3 \end{align}$ $\begin{align} & x=2 \\ & f\left( x \right)=3 \end{align}$ The coordinates of $g\left( x \right)=5$ for $x=-2$ to $x=2$ are as follows: $\begin{align} & x=-2 \\ & g\left( x \right)=5 \end{align}$ $\begin{align} & x=-1 \\ & g\left( x \right)=5 \end{align}$ $\begin{align} & x=0 \\ & g\left( x \right)=5 \end{align}$ $\begin{align} & x=1 \\ & g\left( x \right)=5 \end{align}$ $\begin{align} & x=2 \\ & g\left( x \right)=5 \end{align}$
