Answer:
Explanation:
The relation S is note a function when
2 - |k+1| = -6
Because when they are equal we have two points (-6,4) and (-6,7) in S which implies that -6 is related to two different values.
Now solving
2 - |k+1| = 6
2 - |k+1| = 6
2 - 6 = |k+1|
-4 = |k +1|
But absolute value always non negative, so there is no such k.
