instructions for autist Anonymous 2016-01-21 06:04:46 Post No. 7799265 [Report]
my brain is having autist moment. can anyone help me out with these instructions:

Several intervals can be combined into one region using the "set union" operation, ∪, which is represented as "U" in WeBWorK. For example, [-2,0] U (8,inf) represents the points from −2 to 0 together with everything bigger than 8.

Write the set of points from −5 to 3 but excluding −2 and 3 as a union of intervals
