The inequality is $\"\"$ .

$\"\"$

The function $\"\"$ .

First solve the equation $\"\"$ .

$\"\"$

$\"\"$ .

$\"\"$

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

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

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

Thus, the solution set is $\"\"$ .

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

$\"\"$

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