Work Step by Step

(b) Consider the function: $f\left( x \right)=\left\{ \begin{align} & \text{3 if }x\le -1 \\ & -\text{3 if }x>-1 \end{align} \right.$ The graph of the function f consists of two parallel straight lines also parallel to the x axis. As it can be determined, the range of the function is $\left\{ -3,3 \right\}$. Thus, the range of the function is $\left\{ -3,3 \right\}$.
