Let f(x)= {5-x^2 x
(x+3)/(x-2) x>2
What is the limit as x approaches 2 from the right? I know the answer is 5, but why?

Hi.
I solved the question and weirdly, the correct answer is not 5.
I don't know where you got that number from, but if you've copied the questions accurately, the true answer is positive infinity.
Here's the answer: http://www.4freeimagehost.com/uploads/9d…
The reason why we chose to with (x+3)/(x-2) instead of 5-x^2 is that we're told to get the limit as x is approaching 2 from right; this means that we should chose the piece which belongs to values greater than 2.
Feel free to ask me if you have any additional questions.
Good Luck! :-)
