The inequality is .
The function .
First solve the equation .
.
To find the solution of the inequality , use the intervals
,
, and
.
Interval | Number chosen | value of ![]() | Conclusion |
![]() | ![]() | ![]() | Negative |
![]() | ![]() | ![]() | Negative |
![]() | ![]() | ![]() | Positive |
From the above table, conclude that for all numbers
for which
.
Thus, the solution set is .
Therefore, the solution of is
or in interval notation
.
;
.
