Answer
see graph
Work Step by Step
The graph (red) of $
f(x)=5
$ is a horizontal line passing through $
y=5
.$
The graph (blue) of $
f(x)=3
$ is a horizontal line passing through $
y=3
.$
The graph of the given piecewise function, $
F(x)=
\begin{cases}
5
\text{ if }
x\lt2
\\
3
\text{ if }
x\ge2
,\end{cases}$
is shown above.
