Here is a relation. {(–4, 7), (–2, –1), (–2, 0), (3, 3)} display the relation in an arrow diagram. is the relation a function? explain.

Diagram is attached.  No, the relation is not a function.

In order for a relation to be a function, each input value must be mapped to no more than 1 output value.  One of our input values, -2, is mapped to 2 output values (-1 and 0).  Therefore this is not a function.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
