Description: Value of a fiber of the relation F. (Contributed by Mario Carneiro, 4-Nov-2013.)

Hypothesis

Ref	Expression
shftfval.1	|- F e. _V

Assertion

Ref	Expression
shftfib	|- ( ( A e. CC /\ B e. CC ) -> ( ( F shift A ) " { B } ) = ( F " { ( B - A ) } ) )

Proof of Theorem shftfib

Dummy variables x y z are mutually distinct and distinct from all other variables.
