Which relation is also a function?
{(0, 3), (1, 2), (1, 4), (2, 1))
{(-1,3), (0, 2), (3, -1), (3, 2)}
{(2,-4), (2,-2), (2, 1), (2,3)}
{(-4,-3), (0, -3), (1, -3), (4, -3)}

The correct answer is the final data set: {(-4,-3), (0, -3), (1, -3), (4, -3)}

Step-by-step explanation:

Functions are determined by the x values, which all have to be different. If the same x value appears twice and has a different y value, it is not a function, but if it appears twice with the same y value also, then it is. You can have the same y value twice, but not the x value unless it has the same y value, making the pair exactly the same. Those are the features of a relation being a function. I hope I said that to where it makes sense. Message me if you need clarification.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
