I have a function [tex]z=2x^3+xy^2-6y[/tex](adsbygoogle = window.adsbygoogle || []).push({});

I need to find the limit of the following:

[tex]\lim_{\substack{h\rightarrow 0}} \frac{f(1+h,2)-f(1,2)}{h}[/tex]

I don't know if the function is required to calculate this limit, so I just wrote it as well. I just need some hint on where to begin, and how to approach this type of limit...
