Identify the relation that is also a function. A. {(-1, 1) (0, 0) (1, 1) (2, 4)} B. {(3, 4) (2, 3) (3, 6) (2, 0)} C. {(1, 0) (2, 3) (3, -2) (1, 6)} D. {(3, 2) (3, -2) (3, 6) (3, 8)}

Step-by-step explanation:

We are given four sets of relations as

A function is a relation in which every element in the first set has a unique image in the second set.

Let us check this aspect to A.  

This is a function

Now come to B.  3 has two images 4 and 6.  so not a function

Next is C.  in C 1 has two images 0 and 6.  So not a function

For D, 3 has 4 images so not a function.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
