Choose the critical points from the left hand side.
and
Breakj up the number line into 3 regions:
R1:
R2:
R3:
For each region, choose a point in the region (not an endpoint),
Test the inequality in the region.
R1:
False, R1 is not part of the solution.
R2:
True, R2 is part of the solution.
R3:
False, R3 is not part of the solution.
So then the solution is,
[,)
You cannot include in the solution since the function is not defined at that point.
