Work Step by Step
We have to plot the graph out of functions with the help of the points individually for $f\left( x \right)$ and $g\left( x \right)$.
The co-ordinates of $f\left( x \right)$ for $x=-2$ to $x=2$ are as follows:
$\begin{align}
& x=-2 \\
& f\left( x \right)=-1
\end{align}$
Also,
$\begin{align}
& x=-1 \\
& f\left( x \right)=-1
\end{align}$
Again,
$\begin{align}
& x=0 \\
& f\left( x \right)=-1
\end{align}$
Again,
$\begin{align}
& x=1 \\
& f\left( x \right)=-1
\end{align}$
Again,
$\begin{align}
& x=2 \\
& f\left( x \right)=-1
\end{align}$
The co-ordinates of $g\left( x \right)=4$ for $x=-2$ to $x=2$ are as follows:
$\begin{align}
& x=-2 \\
& g\left( x \right)=4
\end{align}$
Also,
$\begin{align}
& x=-1 \\
& g\left( x \right)=4
\end{align}$
Also,
$\begin{align}
& x=0 \\
& g\left( x \right)=4
\end{align}$
Also,
$\begin{align}
& x=1 \\
& g\left( x \right)=4
\end{align}$
Also,
$\begin{align}
& x=2 \\
& g\left( x \right)=4
\end{align}$
