What is the limit as x approaches 0.5 from the left of the function (2x1)/(2x^3  x^2)?
For some reason, my textbook says the answer is 4, but I keep on getting "does not exist".

Best ResponseYou've already chosen the best response.1The limit is different as x approaches 0.5 from the right

Best ResponseYou've already chosen the best response.1so the limit from 'anywhere' does not exist

Best ResponseYou've already chosen the best response.1 I guess that's not the proper term to use but thats the reason you are getting 'does not exist'.

Best ResponseYou've already chosen the best response.0Ok, but the question asks from the left. I know if the limit was approaching 0.5 then the answer would be 4. But as x approaches 0.5 it's not getting the same answer as in the book.

Best ResponseYou've already chosen the best response.0I just don't see how it's 4 from when x approaches 0.5 from the left.

Best ResponseYou've already chosen the best response.0Unless the textbook meant to ask about x approaching 0.5?

Best ResponseYou've already chosen the best response.1form the left means its approaching from < 0.5

Best ResponseYou've already chosen the best response.1plug in a value of say 0.499 and see what result you get
