Question

Hey! how would u find the limit of lim x->1^+ of 2+x/1-x??

Answer 1

the limit does not exist

Answer 2

\[\lim_{x \rightarrow 1^{+}} 2+x/1-x\]

Answer 3

explain?:)

Answer 4

can it not b - \[\infty\]

Answer 5

if you can factor the (1-x) with something from the top; then you can determine a hole that would be a good value for the limit; but as is; it approaches a vertical asymptote

Answer 6

we can define it as +infinity; but how to define it is ackward

Answer 7

it approaches negative infinity

Answer 8

how did u guys know tht we had 2 graph it?

Answer 9

i didn't graph it

Answer 10

we learn this stuff thru analytical geometry :)

Answer 11

ohh..4 unanalyctical ppl lik me..wud it b poss 2 see tht it wud approach - infiniti by pluggin in points?

Answer 12

the numerical approach is to determine of there is a common factor top to bottom; if so, there is a way to control the function to a common point

Answer 13

without that factoring, the bottom has no way of being reeled in and just goes off into infinity

Answer 14

if the numbers close to the Limit are negative, then yes; its going to - inf

Answer 15

so for \[\lim_{x \rightarrow 0^{-}} (x ^{2}-1/x)\]

Answer 16

its also goin 2 b \[-\infty\]

Answer 17

x^2 -1
------ ?
x

Answer 18

no..x^2- (1/x)

Answer 19

since the x is on the bottom, and the numbers are getting smaller and smaller; the value of the fraction gets bigger and bigger, for example:

1
---------- = 1,000,000
(1/1,000,000)

Answer 20

(x^3-1)/x->-inf as x->0^-
all you have to do is a plug a number in close to 0 from left to determine if you infinity will be negative or positive

Answer 21

so that second part takes over and contiues to add to the function

Answer 22

well, subtract from it in this case :) but...

1,000,000,000,000 - 1,000,000 eventually the fraction is puny in its attempts to control the square and the square takes off into infinity

Answer 23

ohhh...yea i understood it! u explain thm wayy better thn my teacher!:) thank u soo much!..@amistre-u wer the one who helped me lik 3 days ago 2 right?

Answer 24

Answer 35

well, if your ever in florida, yell out the window :)

Answer 36

haha noo..not cuz of tht..jus randomly asked..haha alrighty thn

Answer 37

well..ive got my math final tom..so im ganna b postin tons more up:)

Answer 38

calculus is fun!

Answer 39

good luck, my internet cuts off soon, library closes

Answer 40

yes good luck

Answer 41

thank u :)
