Inputs: -13, 20, 0, -4, 11, -1, 17, (blank space)

Outputs: -15, -11, -9, -2, -1, 5, 5, 13

 

We  have  the points

 

(-13, -15)   ( 20, -11)   ( 0, -9)  ( -4, -2)  ( 11, - 1)  (-1, 5)  ( 17, 5)  ( x, 13)

 

We cannot  have  the  same  x  going to two different y's

 

So

 

-5   is OK

 

-1  is not   ...we  would have  ( -1,5)  and (-1. 13)

 

0  is not......we would have  ( 0, - 9)  and (0, 13)

 

2 is OK

 

11 is not....we would have  ( 11,  -1)  and (11, 13)

 

17 is not....we would  have  (17,5)  and (17,13)
