Which point could be removed in order to make the relation a function? (4 points) {(−4, 3), (−5, 6), (1, 0), (−4, 5), (9, 5), (0, −7)} (−5, 6) (1, 0) (−4, 5) (9, 5)

 The correct option is (C) (-4, 5).

Step-by-step explanation:  We are given to select the point that could be removed in order to make the following relation a function :

R = {(−4, 3), (−5, 6), (1, 0), (−4, 5), (9, 5), (0, −7)}.

We know that

a relation in the form of ordered pairs is a function if each first element is associated to one and only one second element.

In the given relation R, we can see

all the first elements are associated to only one second element except -4.

For -4, there are two second elements 3 and 5 from the ordered pairs (-4, 3) and (-4, 5).

So we can remove one of them to make R a function.

Since (-4, 3) is not in the options, so the correct option is (-4, 5).

Option (C) is CORRECT.

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
