Answer: Think About It In Exercises 3134, determine whether there is a relative maximum
Chapter 13, Problem 31(choose chapter or problem)
In Exercises 31–34, determine whether there is a relative maximum, a relative minimum, a saddle point, or insufficient information to determine the nature of the function f(x, y) at the critical point \(\left(x_{0}, y_{0}\right)\).
\(f_{x x}\left(x_{0}, y_{0}\right)=9, \quad f_{y y}\left(x_{0}, y_{0}\right)=4, \quad f_{x y}\left(x_{0}, y_{0}\right)=6\)
Text Transcription:
(x_0,y_0)
f_xx(x_0,y_0)=9,f_yy(x_0,y_0)=4,f_xy(x_0,y_0)=6
