Theorem mptmpoopabovd 8123
Description: The operation value of a function value of a collection of ordered pairs of related elements. (Contributed by Alexander van der Vekens, 8-Nov-2017.) (Revised by AV, 15-Jan-2021.) Add disjoint variable condition on 𝐷, 𝑓, to remove hypotheses. (Revised by SN, 13-Dec-2024.)
