1.Horizontal asymptotes
horizontal asymptotes is something i dont really get, i mean sometimes i know because i know how the graph looks like but what do i do when i dont know how it looks like? I mean if i use my calculator i could find it but im not allowed to in tests. In the last freeee response in the test i had trouble in the part where it said to state the horizontal asymptote. :-/
2. Behavior of f(x) to the left and to the right of the asymptote
When it comes to end behavior models i completely understand how to find them, but when it asks to describe to describing the behavior graphically of f(x) to the left and the right is when i get stuck :0
3.CONTINUITY AND DISCONTINUITY
ok, discontinuity and discontinuity i sometimes feel safe about, but most of the time i forget what to do or i just go blank. If anyone has an easy way to remember what this is PLEASE tell me D:

1. remember, horiz asymptotes are for end-behaviors, so always look for end-behavior models and then take the limit of it as x-->infinity.
ReplyDelete2. You just have to plug in numbers really close to the left and right of asymptotes.
3. Continuous where you CAN plug in numbers for x, discontinuous where you CANNOT plug in numbers for x.
