Which of the following lists of ordered pairs is a function?

OPTION D.

Step-by-step explanation:

1. A relation is a function if for each value of x there is only one value of y.

2. You can look for in the options the ordered pairs that has only one value of y for each value of x.

3. For example:

A. (3,-2), (2,-1), (3,4), (4,7)

x=3 has two values of y:  (3,-2) and  (3,4); therefore, it is not a function.

4. For the option B, the value x=4 has two values of y, therefore, it is not a function.

5. For the option C, the value x=1 has two values of y, therefore, it is not a function.

Then, the answer is the option D.

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
