(a)

To determine

To calculate: The value of $\underset{x\to 4^{-}}{\lim }f\left(x\right)$ from the function $f\left(x\right)=\{\begin{array}{c}9-2x\text{ if }x<4\\ \sqrt{x-4}\text{ if }x\ge 4\end{array}$.

(b)

To determine

To calculate: The value of $\underset{x\to 4^{+}}{\lim }f\left(x\right)$ from the function $f\left(x\right)=\{\begin{array}{c}9-2x\text{ if }x<4\\ \sqrt{x-4}\text{ if }x\ge 4\end{array}$.

(c)

To determine

To calculate: The value of $\underset{x\to 4}{\lim }f\left(x\right)$ from the function $f\left(x\right)=\{\begin{array}{c}9-2x\text{ if }x<4\\ \sqrt{x-4}\text{ if }x\ge 4\end{array}$.
