The best response is can you do it another way and get the right answer?
Well my goal with inifinite limits - actually all limits - is evaluating what happens when you get closer and closer to a certain x and by rationalizing it I get a more basic function which shows me what truly happens at that point.
Maybe the better question is: If I rationalize this function the domain and range of a normal function is lost and a new function appears how can it be that it still hold the proper value that?
Hello MathisFun forummers,
I stumbles accross this excercise:
and I was thinking why should I rationalize it? The book is very summier about explaining why it has to be rationalized and says it is also a possibility. In the answers it gets rationalized and I understand that I have to do it too, but I don't see the why!?
Thanks in advance
