The inequality is $\"\"$ .

Rewrite inequality as $\"\"$ .

The function $\"\"$ .

First solve the equation $\"\"$ .

$\"\"$

$\"\"$ and $\"\"$ .

$\"\"$

To find the solution of the inequality $\"\"$ , use the intervals $\"\"$ , $\"\"$ , $\"\"$ and $\"\"$ .

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

From the above table, conclude that $\"\"$ for all numbers $\"\"$ for which $\"\"$ or $\"\"$ .

Therefore, the solution of $\"\"$ is $\"\"$ or in interval notation $\"\"$ .

$\"\"$

$\"\"$ ; $\"\"$ .
