### I have the following multivariable function: $f\left(x,y\right)=x{y}^{2}$, and I must prove it is continuous at $\left(1,1\right)$. I have come to: $|{\left({\left(x-1\right)}^{2}+{\left(y-1\right)}^{2}\right)}^{\frac{3}{2}}-1|\le {\left({\left(x-1\right)}^{2}+{\left(y-1\right)}^{2}\right)}^{\frac{3}{2}}+1$ (Triangle inequality) $<{\delta }^{3}+1=ϵ$. What can I do with this 1? Any tips are welcome and thank you in advance!
