Work Step by Step

Step 1. Graph the function $y=3^x$; as the inequality includes an equal sign, make the boundary solid. Step 2. Using a test point away from the boundary, such as $(0,0)$, we have $0\lt3^0=1$ which is true; thus the side with this test point should be shaded as shown in the figure.
