Blogging before the test... again.

This unit about functions isn't so bad at all. The only that's confusing is questions about finding the domain and range of this kind of question:

{x,y|y=2x-1}

The only thing I know about this kind of problem is to find its domain. The range is I think y is greater than or equal to -1. But then again, I don't really know. Function of x is the really topic I had fun with, as it only involved substitutions of variables.

Other than that, I wish everyone luck for tomorrow's test, and Merry Christmas and a Happy New Year!
