$\left(a\right)$

To determine

The graph of the function $f\left(x\right)=\left\{\begin{array}{l}5-x,x\ne 2,\\ -3,x=2\end{array}\right.$ .

$\left(b\right)$

To determine

To evaluate: $\underset{x\to 2}{\lim }f\left(x\right)$ .

$\left(c\right)$

To determine

To evaluate: $f\left(2\right)$ for the function $f\left(x\right)=\left\{\begin{array}{l}5-x,x\ne 2,\\ -3,x=2\end{array}\right.$ .

$\left(d\right)$

To determine

Whether the function $f\left(x\right)=\left\{\begin{array}{l}5-x,x\ne 2,\\ -3,x=2\end{array}\right.$ continuous at $x=2$ .
