Suppose the function f (x, y, z) = 2x – 3y + z – 20 gives the temperature, in degrees Fahrenheit, at a point (x, y, z). (a) Describe the isothermal surfaces of f. (b) Calculate and interpret f- (0, 0,0). (c) If you are standing at the point (0, 0, o), in what direction should you move to increase your temperature the fastest? (d) Is f (x, y) = -2x + 3y + 17 an isothermal surface of f? If so, what is the temperature on this isotherm?
