What set would no longer be a A function if the ordered pair(5,3) was added
Delicious77 [7]
The answer is D because a function means for every input  you get exactly one output so
for every x you get one y
in D there is a coordinate (5,2) meaning that if you put in 5 for x you get 2 for y

but the new ordered pair also  has 5 for x but has a difarent y value.  this violates the definition of a funciton
