Answer
$Amplitude$ $=$ $3$
$Period$ $=$ $2$
Work Step by Step
The highest point (amplitude) in the graph is at $y = 2$
$Divide$ $the$ $natural$ $period$ $of$ $a$ $sine$ $wave$ $2π$ $to$ $the$ $coefficient$ $of$ $x$ $inside$ $the$ $trigonometric$ $function$:
$Period$ $(T)$ $=$ $\frac{2\pi}{\pi}$ $=$ $2$
