Which relation represents a function?

The relation which represents a function is:

           { (-2,2) , (0,2) , (7,2) , (11,2) }

Function--

A function is a relation such that each element of first set is mapped to a unique element of the other set.

i.e. no element has two images.

i.e. it is  a ordered pair of the type: (x,y)

such that no x is mapped to more than one y.

A)

{ (0,0) , (2,3) , (2,5) , (6,6) }

It is not a function.

since 2 is mapped to 3 i.e. the ordered pair (2,3)

and 2 is mapped to 5 as well i.e. the ordered pair (2,5) .

B)

{ (3,5) , (8,4) , (10,11) , (10,6) }

It is not a function.

since 10 is mapped to 11 in the ordered pair (10,11).

and 10 is mapped to 6 in the ordered pair (10,6) .

C)

{ (-2,2) , (0,2) , (7,2) , (11,2) }

It is a function.

since no element of the  first set is mapped to more than one element of the other set.

D)

{ (13,2) , (13,3) , (13,4) , (13,5) }

It is not a function.

since 13 is mapped to more than one element of the other set.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
