Theorem rnmpo 6189

Description: The range of an operation given by the maps-to notation. (Contributed by FL, 20-Jun-2011.)

Hypothesis

Ref	Expression
rngop.1	|- F = ( x e. A , y e. B |-> C )

Assertion

Ref	Expression
rnmpo	|- ran F = { z | E. x e. A E. y e. B z = C }

Distinct variable groups:   y, z, A   z, B   z, C   z, F   x, y, z

Allowed substitution hints:   A( x)   B( x, y)   C( x, y)   F( x, y)
