Question

Question 3 Danah created a list of ordered pairs, as shown below: (0, 2), (3, 4), (4, 4), (5,6), and (5,8) Which statement explains why her set of ordered pairs is not a function? There are two y-values of 4, even though their x-values are different There are two X-values of 5, even though their y-values are different. C There is an ordered pair where the x-value and the y-value are the same. There is not a constant rate of change between the pairs. ©2021 Illuminate Education TM Inc.

Answer 1

Option B is correct.

There are two X-values of 5, even though their y-values are different.

Step-by-step explanation

A function is an expression that takes up each value of an independent variable (x) and gives a corresponding value of a dependent variable (y) without the same values of the independent variable (x) giving different values of the dependent variable (y).

With the ordered pairs written as (x, y), we can see that 5 occurs two different times, with different y values in the two cases. This disqualifies the relation from being a function.

Hope this Helps!!!
