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:
$f(-1)=\frac{5}{3}^{-1}=\frac{3}{5}=0.6$
$f(0)=\frac{5}{3}^0=1$
$f(1)=\frac{5}{3}^1=\frac{5}{3}\approx 1.67$
$f(2)=\frac{5}{3}^2=\frac{25}{9}\approx 2.77$
