If a function f is continuous at x0, then its limit as x -> x0 is f(x0).

Using what "basis"? If you know about "continuous functions" and in particular that all polynomials are continous for all values of x then it is sufficient to say, as emakarov does, that the limit is .

If, on the other hand, you have only the**definition**of limit to work with, you need to look at , then what can you say if you choose so that becomes ? - Jun 14th 2012, 12:54 PMrichard1234Re: Prove this limit
The function is continuous everywhere.

Therefore
