You can put this solution on YOUR website!
Arguments for the square root function must be non-negative.

Break up the number line into three regions.
.
.
.
Region 1:(  ,  ]
Region 2:[  ,  )
Region 3:(  ,  )
.

.
 is allowed,  is not allowed since the function is undefined.
.
.
.
Choose a point in each region (not an endpoint).
Test the inequality.
If the inequality is satisifed, the region is part of the solution.
.
.
.
Region 1:

True, this region is part of the solution region.
.
.
.
Region 2:

False, this region is part of the solution region.
.
.
.
Region 1:

True, this region is part of the solution region.
