A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
![S= \{(2-|k+1|,4), (-6,7)\}](https://tex.z-dn.net/?f=S%3D%20%5C%7B%282-%7Ck%2B1%7C%2C4%29%2C%20%28-6%2C7%29%5C%7D)
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
![2-|k+1| = 6](https://tex.z-dn.net/?f=2-%7Ck%2B1%7C%20%3D%206)
Collect like terms
![-|k+1| = 6 - 2](https://tex.z-dn.net/?f=-%7Ck%2B1%7C%20%3D%206%20-%202)
![-|k+1| = 4](https://tex.z-dn.net/?f=-%7Ck%2B1%7C%20%3D%204)
Multiply by -1
![|k+1| = -4](https://tex.z-dn.net/?f=%7Ck%2B1%7C%20%3D%20-4)
Remove absolute bracket
![k+1 = -4\ or\ k+1 = 4](https://tex.z-dn.net/?f=k%2B1%20%3D%20-4%5C%20or%5C%20k%2B1%20%3D%204)
Solve for k
![k =-1 -4\ or\ k= -1+4](https://tex.z-dn.net/?f=k%20%3D-1%20-4%5C%20or%5C%20k%3D%20-1%2B4)
![k =-5\ or\ k= 3](https://tex.z-dn.net/?f=k%20%3D-5%5C%20or%5C%20k%3D%203)
Hence, when k is 5 or 3, the relation will not be a function.
