Best ResponseYou've already chosen the best response.0clearly domain is \(\mathbb{R}^2\) and for relative extrema we have\[\frac{\partial f}{\partial x}=2x=0\]\[\frac{\partial f}{\partial y}=e^y=0\]we should solve these equations simultaneously but u r right...answer is none because for all real values of y we have\[e^y>0\]
