Which of the sets of ordered pairs represents a function? (5 points) a = {(1, −5), (8, −5), (8, 7), (2, 9)} b = {(7, −4), (7, −2), (6, −3), (−9, 5)}

Step-by-step explanation:

For any function,any point in the domain has a unique image in the codomain.

For set :

from the point

from the point

For a same point ,there are two images.

So, does not represent a function.
