Question

{-7,4),(-8,3),(-7,7),(-20,8),(5,9),(3,1),(2,6)} is it functions or not ?

Answer 1

Answer:

It is not a function

Step-by-step explanation:

{(-7,4),(-8,3),(-7,7),(-20,8),(5,9),(3,1),(2,6)} is not a function as -7 is the first element to two ordered pairs, i.e. it's not unique to the elements of the second set that appear as the second element of the given ordered pairs.

therefore, it is not a function.
