Work Step by Step
1. The inequality sign is $\leq $, so we draw a solid border
2. The border, $y=3^{x}$
is an exponential function, base $>1,$
Plot some points (see table)
and join with a smooth (solid) curve
3. Test the point $(0,0)$
$ 0 \leq 3^{0}\quad ?$
$0 \leq 1\quad ?$
Yes
4. Shade the region that the origin belongs to.
