Limit multivariable function

[GDF]

Can someone give me a hint of how to solve this problem? I have to find the limit or show that it does not exist. I have tried many paths ( x=y, x=1, y=x^2) but still can't prove it does not exist.

Please show your work on some of the paths you tried, and what limits you got. If you got different limits, then you've proved the limit doesn't exist!
