Question

does the limit 0 and negative infinity mean the same?

Answer 1

no.

Answer 2

negative infinity means..
-1 -2 -3 -4 ......... (and so on)

Answer 3

limit zero is 3 2 1 and 0.

Answer 4

im still confused why at times you can plug in infinity or negative infinity and 0 at other times to get the limit...

Answer 5

for example, in this link http://tutorial.math.lamar.edu/Classes/CalcI/LimitsAtInfinityI.aspx#Limit_LimAtInf_Ex1a look at example 4 and 5... why can't we use the infinty to plug in for both examples?

Answer 6

Sorry, i dnt rmmbr Calculas now. :/

Answer 7

thanks for working anyway!

Answer 8

lim x ---> a number (including 0) is asking you what happens as we get really close to that number, where is y going?


lim x ---> infinity is asking what happens as x gets closer and closer to infinity. With this kind of problem, if the answer is infinity or neg infinity, it just means the value of y will keep growing infinity larger or smaller. If you hit a number as a limit, it means you are hitting an asymptote which is somewhere x is not defined, and so it will always be getting closer and closer to that number, but it will never actually hit that number

Answer 9

not the same thing
