Answer 4

good. but there is one thing that is the most important and it is that in a function a certain x-value cannot be repeated.

for instance:
(1,3) (2,5) (1,-4) is not a function because the x-value of 1 is being repeated twice.

in simpler terms, in a function a certain x-value cannot have two y-values.
