Hi(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to prove the continuity of a function. I do understand the definition and I can do it for "smaller" functions. However, for this "larger" function I am having troubling bounding it and thus can't find a prove. Any suggestions would be greatly appreciated!

Show, using the epsilon-delta definition, that the following function is continuous: f(y) = 1 / (y^4 + y^2 + 1).
