. Graph the relation. Is the relation a function? Why or why not?
{(-1, 1), (-2, 1), (-2, 2), (0, 2)}

Yes; there is only one range value for each domain value.

No; a range value has two domain values.

No; a domain value has two range values.

Yes; there is only one domain value for each range value.

The answer is letter B "No; a range value has two domain values".

For a relationship to be a function, there must be a one-to-one correspondence between the x and y values.  For every value of x, there must be only one value for y.  So the first set is a function and the second set is not.

No; a range value has two domain values.

Step-by-step explanation:

Output has to be unique for all inputs.

Output for -2 is not unique

Step-by-step explanation: It is either B or C

Since  

x  =  − 2

produces  

y  =  1

and  

y  =  2 , the relation  

( − 1 ,  1 ) ,     ( − 2 ,  1 ) ,     ( − 2 ,  2 ) ,     ( 0 ,  2 )

is not a function.

The relation is not a function.

No; a range value has two domain values

Step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

answer is x<
