Technically I'm taking Calculus, but this is still in the range of Algebra I believe.
The question is:
And all we have to do is state the intervals for the domain. So I have (-INF, -6],[-3,INF).
But it's asking for three intervals, and I'm not sure what to put in the third one.
We're using an online system,, so it's possible it could be a bug I suppose, but if not, I'm not sure what I'm missing.
