Question 15 of 16
Westkost [7]

The same input is being mapped into two outputs, so this is not a function.

<h3>Does the table represent a function?</h3>

A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.

Here we have the table:

x    y

4   2

3   3

4   5

5   6

7   7

As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.

Then this table does not represent a function.
