Question

Find the value lim x->infinity (6x^2-1)/(x^3-5x+2)

Answer 1

I don't really like limits at infinity, but...

If you plug in infinity, you get (looking at the terms with the highest power) infinity squared over infinity cubed. Multiply top and bottom by 1/infinity^2 and you get 1/infinity, which is zero.
