f(x)=\sin x+2

First, let's find the value of f(x) along the midline x = 0:


\begin{gathered} f(0)=\sin 0+2 \\ f(0)=2 \end{gathered}

Then, the point at the midline is (0,2)

The minimum point nearest the midline is:


\begin{gathered} f(-(\pi)/(2))=_{}f(-1.57) \\ f(-(\pi)/(2))=\sin (-(\pi)/(2))+2 \\ f(-(\pi)/(2))=-1+2 \\ f(-(\pi)/(2))=1 \end{gathered}

Analogously, the maximum point nearest the midline is:


\begin{gathered} f((\pi)/(2))=_{}f(1.57) \\ f((\pi)/(2))=\sin ((\pi)/(2))+2 \\ f((\pi)/(2))=1+2 \\ f((\pi)/(2))=3 \end{gathered}

Then the graph is given by:
