Find a value of constant "k" so a limit to infinity exists 1. The problem statement, all variables and given/known data Find a value of the constant k such that the limit exists. 2. Relevant equations lim x to infinity of x^3-6/x^k+3 3. The attempt at a solution I started by setting the equation equal to infinity and attempted to rearrange it but got pretty much nowhere. I also broke it up using limit rules and also ended up nowhere.
