Question
Suppose that between the utility functions u (x, y) and v (x, y) there exists the relation v (x, y) = f (u (x, y)). Say which of the following functions
they can be used as utility functions and why.
1. f (u) = 5000 - 23u
2. f (u) = log10 u
3. f (u) = e ^ u
4. f (u) = 1 / u
5. f (u) = | u |
Explanation / Answer
Functions 2, 3, 5 can be used as utiity functions, This is because these are the monotonic transformation of the function u.
