Hey, once again, I've completed the problem already, just want to check my work.
Thanks in advance.
(Not really sure what work/answer needs to be shown... but I've posted what I got also)

lim(x/5)= 3/5 X->3
I Got: 5epsilon

lim(x/4)+3= 9/2 X->6
I Got: 4epsilon

lim( (x^2+x-6) / (x-2) )= 5 X->2
I Got: epsilon

lim( (9-4X^2) / (3+2x) )= X->-1.5
I Got: epsilon/2

lim(x)= a X->a
I Got: epsilon

lim( x^2 - 4x + 5 )=1 X->2
I Got: sqrt(epsilon)

lim( x^2 - 1)= 3 X->-2
I Got: epsilon/5


Get Workin'!:stirthepot:

Edit: Added the answers I got

Wolfram alpha wont even touch it: (

ugh, this is definitely one of those things I forgot most of.

I question the second to last one:
lim( x^2 - 4x + 5 )=1 X->2
I Got: sqrt(epsilon)

It seems to me you can't square root epsilon.

Proofs were never my strong point. I don't think I could be of any more help.

do you actually get tested on this? Feel sorry for ya

Quiz on it tomorrow, and will have a few (2-3?) problems on the test about it.
Really think so? At first it was hard shit, and now its easy as diarrhea, I can blaze though the problems really fast, looking forward to some free points on the quiz which I need!
