Can some one help me with limits? I'll write the equation below.

Question

anonymous · Answer

$$\lim_{x \rightarrow -3}     [1/ (x+3)^{4}] = infinity$$

anonymous · Answer

it's infinity since lim(x to a) (1/x) is infinity - this the general idea.. :)

anonymous · Answer

how do you prove it?

anonymous · Answer

drawing a graph will be good answer for this. :) 
hmm... you know the general quotient limit laws ya?  :) lim(x to a) c, where c is constant is simply c. 
lim (x to a) 1/x is simply 0. 
because of your question will give you , 1/0 - which not possible, then it'll be infinity.. 
but u have to make sure that the function is polynomial and continuous.. :)

dont u have to show work

anonymous · Answer

my teacher shows work and write some statements with delta and epsilon.

anonymous · Answer

i dont understand it

anonymous · Answer

I don't really know the long way, since I skip it using applying the general limit laws into my work.. save ink.. :)
if that's the case, then I could not help you further.. :) sorry..
