Ok, I have 2 problems. I think my first one deals with an algebra II thing. But, it's: Evaluate the limit (if it exists):(adsbygoogle = window.adsbygoogle || []).push({});

lim (x approaches -2) (x+2)/(x^3 +8)

I think my problem came from factoring the denominator, which I got as

(x+2)(x^2 - 4x +2), so my answer came out to be 1/14, which is not one of the answer choices. I can't remember factoring cubes. I know it's SOPSMS, but I can't even remember how to do that.

My other problem. Can anyone give me an example of finding the gradient of a function at, say x=3, for something that has an exponent with a variable? Maybe 4^x. Thanks!!!!!!!
