Question

Question 15 of 20Which of the following lists of ordered pairs is a function?OA. (2, 5), (3, 8), (4, 11), (4, 12)O B. (1,7), (2, 5), (3, 6), (4,1)OC. (3,-2), (2, -1), (3, 4), (4,7)O D. (0,4), (1, 2), (1, 0), (2, 3)

Answer 1

`B.\text{ }(1,7),\text{ }(2,5),\text{ }(3,6),\text{ }(4,1)`

Step-by-step explanation

We want to identify the list of ordered pairs that does not represent a function.

Ordered pairs are written in the form (x, y) where x represents the values in the domain and y represents the values in the range.

A list of ordered pairs represents a function if each value in its domain is mapped to only one distinct value in its range. In other words, no value in the domain corresponds to two different values in the range.

Therefore, the list of ordered pairs that represent a function is:

`\begin{equation*} (1,7),\text{ }(2,5),\text{ }(3,6),\text{ }(4,1) \end{equation*}`

The correct answer is option B.
