Best ResponseYou've already chosen the best response.1I can do the lim, but how do i do it on that:O it lin x>1

Best ResponseYou've already chosen the best response.1What is the limit for the function x^2  1 as it approaches 1?

Best ResponseYou've already chosen the best response.1Hmm, not quite. You want to approach x = 1.

Best ResponseYou've already chosen the best response.1Follow the graph of x^2 1 as it approaches x =1. What is the yvalue?

Best ResponseYou've already chosen the best response.1Sorry *.* i'm not very good a limits:(

Best ResponseYou've already chosen the best response.1Yes :) then follow the graph of 4x as it approaches x=1. You start from the right hand side and move back till you reach x=1.

Best ResponseYou've already chosen the best response.1What would you say the limit was for that equation?

Denebel

Best ResponseYou've already chosen the best response.1Ok, are the two limits for both equations the same?

Best ResponseYou've already chosen the best response.1Nope. Oh:3. Dur dur. You compare the 2 equations:3

Best ResponseYou've already chosen the best response.1@Denebel one last Q. It also says to find x>+ and . In this cast, thats DNE too. right?

Denebel

Best ResponseYou've already chosen the best response.1Nope, as x>+ means when x approaches a number (in this case, 1) from the right hand side. x> means when x approaches (1) from the left hand side.

Best ResponseYou've already chosen the best response.1But those are not the same for either left or right.

Best ResponseYou've already chosen the best response.1You only need to make sure they are the same when they don't give you a +/ Since the next part of the problem asks you to state the limit when it comes from +, then when it comes from  you say what you told me before. So when x> 1+ is when it approaches x=1 from the right side. You only look at the function 4x in this case. x> 1 is when it approaches x=1 from the left side, so look at the function x^2  1

Best ResponseYou've already chosen the best response.1Oh so you only look at each problem separately then :O

Best ResponseYou've already chosen the best response.1so lim x>1 = 0 and + = 3 and x> = DNE
