In Exercises 61–64, find an equation for the level surface of the function through the given point.
Test the functions in Exercises 65–68 for local maxima and minima and saddle points. Find each function’s value at these points.
65. . ƒ(x, y) = 2x3 + 3xy + 2y3
66. ƒ(x, y) = x3 + y3 - 3xy + 15
67. ƒ(x, y) = x3 + y3 + 3x2 - 3y2
68. ƒ(x, y) = x4 - 8x2 + 3y2 - 6y
In Exercises 65–68, find and sketch the domain of ƒ. Then find an equation for the level curve or surface of the function passing through the given point.
