3 because the x value has been repeated

3) {(−1,6),(1,3),(2,5),(1,7)}

Step-by-step explanation:

functions have to pass the vertical line test to be called a function

if they don't pass they are <em><u>not</u></em> a function

this means that no x values can repeat

In option 1

none of the x values repeat so that means it <em><u>is</u></em><em><u> </u></em>a function

1, 2, 3, 4

in option 2

none of the x values repeat so that means it <em><u>is</u></em><em><u> </u></em>a function

4,2,-3,3

in option 3

one of the x values repeats so that means it is <em><u>not</u></em><em><u> </u></em><u>a</u><u> </u><u>func</u><u>tion</u>

-1,<em><u>1</u></em>,2,<em><u>1</u></em><em><u> </u></em> the ones repeat

in option 4

none of the x values repeat so that means it <em><u>is</u></em><em><u> </u></em>a function

-1,0,5,2

so that means that <em>option 3 is not a function </em>
