Adding which of the following ordered pairs to the set {(0, 1), (2, 4), (3, 5)} would make it not a function?

(1, 6)
(4, 2)
(0, 7)
(7, 0)

Where’s the stuff st? ? lol sorry

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
