Domain of a Function

I have removed all annotations from my videos that were used to correct errors (YouTube is getting rid of Annotattions) Any errors in the videos have been corrected in the NOTES.

CORRECTION: On minute 1:50 it should read (2x-3)/(2x+3) In this video I explain what the domain of a function is and how to calculate it. I give you eight examples about calculating the domain of a function involving square roots, reciprocal, rational functions and absolute values. There is a second video about this, here: http://bit.ly/2i90EvF .
