$\"\"$

The inequality is $\"\"$ .

Draw a coordinate plane.

Graph the functions $\"\"$ and $\"\"$ on the interval $\"\"$ in the same window.

$\"\"$

Observe the graph :

The two graphs intersects at $\"\"$ and $\"\"$ .

The graph of $\"\"$ is at or below the other graph $\"\"$ when $\"\"$ .

Therefore, $\"\"$ on $\"\"$ . $\"\"$

The solution set is $\"\"$ .
