hi Olden
for this problem you will need l'Hospital's rule.do you know it?
I thought when i did not have lim x->infinity that i had to change the top x^3 - 2x +1 into something else. Like if i had lim x->2 x^2-2x / x^2-3x+2 = 0/0 i would make lim x->2 x(x-2) /(x-2)(x-1) = x/x-1 = 2. And i don't know how to do this when i have x^3. Sorry if i explain badly
