Show that if A andBare sets|A| = |B|then P (A) = P (B) .
Short Answer
If g is one-to-one and onto, g is one-to-one correspondence from P (A) to P (B) is P (A) = P (B) .

Get started for freeDraw the graph of the function f(x) = [x] + [x/2] from R to R.
For each of these partial functions, determine its domain, codomain, domain of definition, and the set of values for which it is undefined. Also, determine whether it is a total function.
