-2(x+3) is less than or equal to -10 for values of x greater than or equal to 2 -- notice the negative 2 out front.

What I take exception to is the grading rubric for page 13 on that test.  Students are to sort values into three columns.  Partial credit is given if 2 of the 3 columns are correct.  How in the heck is that supposed to happen?  Misplacing one value messes up two columns.  Hence, no credit.

The domain - the "legal" values for x in this case - is restricted to values greater than or equal to 2, so no negative values for x would be used.
