Question

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

Answer 1

Both sets represent a function.

Explanation:

Both sets represent a function because in both sets, each x value yields a specific y value.

Answer 2

Answer: Both A and B are representing a function.

Explanation:

• A relation is said to be function its each input value (x) corresponds to a unique output value (y).

For the function A = {(3, −5), (4, 6), (−3, 9), (2, 7)}

Here , each input value (x-value : 3,4,-3,2) corresponds to a unique out put value (y-value : -5,6,9,7), that means A is a function.

B = {(2, 4), (−1, −7), (5, 6), (4, 3)}

Here, each input value (x-value : 2,-1,5,4) corresponds to a unique out put value (y-value : 4,-7,6,3), that means B is a function.

Hence, Both A and B are representing a function.
