Chapter 13, Problem 27

(choose chapter or problem)

 Describe the domain of \(f\) in words.

(a) \(f(x, y)=x e^{-\sqrt{y+2}}\)

(b) \(f(x, y, z)=\sqrt{25-x^{2}-y^{2}-z^{2}}\)

(c) \(f(x, y, z)=e^{x y z}\)

Equation Transcription:

f

f(x, y)=xe^-sqrt y+2

f(x, y, z)sqrt 25-x^2-y^2-z^2

f(x, y, z)=e^xyz
