Answer
See the picture below.
Work Step by Step
By calculating a few pairs and connecting the dots on the graph with a smooth curve, we graph the function.
A few pairs:
$f(-1)=\frac{3}{2}^{-1}=\frac{2}{3}\approx 0.67$
$f(0)=\frac{3}{2}^0=1$
$f(1)=\frac{3}{2}^1=\frac{3}{2}=1.5$
$f(2)=\frac{3}{2}^2=\frac{9}{4}=2.25$
