Answer:
D = 4, 4, 6, 7
R = 2, -1, 3, 5
Function? It is NOT A FUNCTION
Step-by-step explanation:
Domain (D) include the set of input values, while the Range includes the set of output value (y).
Thus:
Note that the input value, 4, is mapped or is related to two different output values, 2 and 5. Therefore,
D = 4, 4, 6, 7
R = 2, -1, 3, 5
✔️It is not a function because there are two output value related to one input value.
