f(x)=\left\{\begin{array}{cc}x+2, & , x>1 \\2 & ,-1 \leq x \leq 1 \\x-1, & -3<x<-1\end{array}\right.

\begin{aligned}&f(x)=x+2 \quad x=2,3\\&f(x)=2 \quad x=-1,0,1\\&f(x)=x-1 \quad x=-2,-1.5\end{aligned}

(i) $\mathrm{f}(3)\\f(x)=x+2$\\$f(3)=3+2=5$\\$\therefore {f}(3)=5$

\begin{aligned}&\text { (ii) } \mathrm{f}(0)\\&f(x)=2\\&\therefore f(0)=2\end{aligned}

(iii)  f(-1.5)$

f(x)=x-1

f(-1.5)=(-1.5)-1

\therefore f(-1.5)=-2.5

\begin{array}{l}\text { (iv) } f(2)+f(-2) \\\text { f(2) }=f(x)=x+2 \\\end{array}

\begin{array}{l}f(2)=2 \\f(-2)=f(x)=x-1 \\\end{array}

\begin{array}{l}f(-2)=-2-1=-3\\\therefore f(2)+(-2)=4+(-3) \\\end{array}

\begin{array}{l}\therefore f(2)+(-2)=1\\\end{array}
