Best Way to graph Rational Algebraic Functions? (1 Viewer)

Whats the best way? ie. like find asymtotes, turning points etc?

this is ext 1 stuff isn't it?
anyways....
i would use calculus to find turning points etc.
then use limits i.e. lim x --> +/- oo, lim x --> 0
or u could observe the denominator and determine vertical asymptotes that way.

Its in the 2 unit book. However it may also be in the three unit book, i havent checked. Thanks that was what i was looking for, sane way i do it.

generally, looking at intercepts and turning points gives a good indication of what the graph looks like. however, it's not always like that.
e.g. in a practice trial paper i did yesterday, i forgot to graph the function for x<0. i won't forget to do that from now on, but it's another common mistake that can be made.

The 2 unit ones are just basic normally with x to the power of one as a denominator
