Yes, it is a function.
In order for a set of ordered pairs to represent a function, each element in the domain must be paired with exactly one element in the range. Let's examine the given domain and range:
Domain: -8, -2, 1, 4
Range: -10, 0, 10, 0
If we pair each element in the domain with its corresponding element in the range, we get:
(-8, -10)
(-2, 0)
(1, 10)
(4, 0)
Each element in the domain is paired with exactly one element in the range, so this set of ordered pairs represents a function.
Therefore, the answer is yes, it is a function.
Question:
If your domain is -8,-2,1,4 and your range is -10,0,10,0 would this be a function yes or no
