Break up the number line into 3 regions using the critical points of the function.
Region 1:(,)
Region 2:(,)
Region 3:(,)
.
.
.
For each region, choose a point in the region (not an endpoint).
Test the inequality.
If the ineqaulity is satisfied, the region is part of the solution region.
.
.
Region 1:
True, Region 1 is part of the solution region.
.
.
Region 2:
False, Region 2 is not part of the solution region.
.
.
.
Region 3:
True, Region 3 is part of the solution region.
.
.
.
Solution Region: (,) U (,)
.
.
.
Graphical verification: Look for regions where the function is above the x-axis ().
