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)}

Group of answer choices

Only A

Only B

Both A and B

Neither A nor B

We are given to select the correct set of ordered pairs that represent a function :

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

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

We know that

A set of ordered pairs represents a function if each first element is associated with unique second element.

In set A, we see that no first element is associated to more than one second element. So, the set A represents a function.

In set B also, we see that each first element is associated to a unique second element. So, the set B is also a function.

Thus, both the sets A and B represents a function.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
