Question 1039284
<font face="Times New Roman" size="+2">


You are right, the answer is not 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \left\[-1.23,0\right\]] *[tex \large\cup]  *[tex \LARGE \left\[1.44,\infty\right\]].


That is because *[tex \Large \infty] is NEVER included as an endpoint of an interval. If you include an endpoint in an interval, that endpoint must be a number, but *[tex \Large \infty] is not a number. The correct answer to the problem is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \] [-1.23,0]*[tex \large\ \ \cup\ \ ][1.44,*[tex \LARGE \infty]).

My calculator said it, I believe it, that settles it
