Theorem relmpoopab 8095

Description: Any function to sets of ordered pairs produces a relation on function value unconditionally. (Contributed by Mario Carneiro, 9-Feb-2015.)

Hypothesis

Ref	Expression
relmpoopab.1	⊢ 𝐹 = (𝑥 ∈ 𝐴, 𝑦 ∈ 𝐵 ↦ {⟨𝑧, 𝑤⟩ ∣ 𝜑})

Assertion

Ref	Expression
relmpoopab	⊢ Rel (𝐶𝐹𝐷)

Distinct variable groups:   𝑥,𝑤,𝑦,𝑧   𝑦,𝐵   𝑥,𝐴,𝑦

Allowed substitution hints:   𝜑(𝑥, 𝑦, 𝑧, 𝑤)   𝐴(𝑧, 𝑤)   𝐵(𝑥, 𝑧, 𝑤)   𝐶(𝑥, 𝑦, 𝑧, 𝑤)   𝐷(𝑥, 𝑦, 𝑧, 𝑤)   𝐹(𝑥, 𝑦, 𝑧, 𝑤)
