Question 3 Given the relation: {(6, 0), (3, -6), (2, -3), (1, -1), (-4, 5), (3, 4), (5, 5)). Is this a function? Why or why not? O No, it is not a function, because the number 5 corresponds to two different numbers. O Yes, it's a function, because every number is paired with another. O Yes, it's a function, because of the notation used. O No, it is not a function, because the number 3 corresponds to two different numbers. Question 4
