What exactly are we trying to work out here?
Answer:
B. The relation is a function because each x-value corresponds to only one y-value.
Step-by-step explanation:
In order for a relation to be a function, each x-value must have only one y-value. Decimals and negative numbers are negligible.
The x-coordinate of D is 7 greater than that of A.
The y-coordinate of D is 3 less than that of A.
The appropriate choice for the description of the mapping is
... (x+7, y−3)
