2 Questions
1. my first question is about questions 7 and 8 on the pretest: how do you justify the domains algebraically?
2. what is an asymptote (like in question 14 on the pretest)?
thanks

An asymptote is a line that the graph is appraoching but never reaches. Like 2^x=y approaches zero but never reaches it.
For 7 and 8, you can show than the denominator of 7 can't equal cro and the square root can't be nagative. In 8, you can show thtat anything aquared is positive and then work from that.
