Answer:
A. No; two range values exist for domain value –2.
Step-by-step explanation:
In a function each input has ONE output. -2 has two range values, so No; two range values exist for domain value -2.
The given relation is
We need to check whether the above relation is a function or not.
A relation is a function if there exist a unique value of y for each value of x.
From the given relation it is clear that
y = 0 at x = -2
y = 6 at x = -2
Two range values exist for domain value –2. So, the given relation is not a function.
