Use complete sentences to describe the relation in terms of a function. f = {(2, -4), (2, 7) (3, 5), (4, -1), (8, 7)}

The relation F is not a function

Step-by-step explanation:

A relation is a function if and only if for each input value x, there is a single output value y.

If for an input value x there are two or more output values y then the relation is not a function.

In this problem we have the following relationship:

F = {(2, -4), (2, 7) (3, 5), (4, -1), (8, 7)}

Note that for the input value there are two possible output values: ,  .

Therefore, based on the definition described above, the relation F is not a function

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

b). 4320 have a nice day
