__________
The picture below shows 3 Examples, They are color coded. Which is a function and which is not a function.

Brown:

Orange:

Pink:

Answer 1

Orange

Explanation:

Function means for same
`x` there can not be two different
`y`.

We observe in the Brown table there is
`(3,-2) \ and\  (3,2)` - here at same
`x=3`There exists two different
`y`. Thus it is not a function.

Similarly in Pink table, there are two dots at same
`x` meaning there are two different
`y` at same
`x=1` which is not possible. Thus that is also not a function.

Therefore only Orange has all
`x` unique, that is the function.
