evaluating limits numerically.

Fill in the following table to find $\displaystyle \lim_{x\to-2}f(x)$ where $\displaystyle f(x)=\frac{x^3+2x^2-x-2}{x^2-4}$. Give table values to *four signifigant digits.*

___x__-2.5__-2.1__-2.01__-2.002__-2.0001__-2.00001__-2__

__f(x)_____________________________________________?__

___x__-1.5__-1.9__-1.99__-1.999__-1.9999__-1.99999__-2__

__f(x)_____________________________________________?__

Based on this table *my estimate*, to two significant digits, for $\displaystyle \lim_{x\to-2}f(x)=$____?_____

Anybody?

Hey guys. I can pretty much do the table, but I put it up there so that you guys would understand that we are evaluating the limit *numerically*, not algebraically. That's why we were asked to give an answer to with the given margin of error. Anybody got any ideas ?

Is this a bad question or something? usually I get a much quiker response.
