Description: An operation's value belongs to its range. (Contributed by AV, 27-Jan-2020.)
Hypothesis
Ref Expression
ovmpoelrn.o 𝑂 = (𝑥𝐴, 𝑦𝐵𝐶)
Assertion
Ref Expression
ovmpoelrn ((∀𝑥𝐴𝑦𝐵 𝐶𝑀𝑋𝐴𝑌𝐵) → (𝑋𝑂𝑌) ∈ 𝑀)
Distinct variable groups:   𝑥,𝐴,𝑦   𝑥,𝐵,𝑦   𝑥,𝑀,𝑦
Allowed substitution hints:   𝐶(𝑥, 𝑦)   𝑂(𝑥, 𝑦)   𝑋(𝑥, 𝑦)   𝑌(𝑥, 𝑦)
