Question

Can somebody help me with this

Answer 1

Answer:

D = -1, -1, 2, 5

R = 0, 2, 3, 7

✅It is NOT A FUNCTION

Step-by-step explanation:

D (Domain) = input values (x-values)

D = -1, -1, 2, 5

R (Range) = output values

R = 0, 2, 3, 7

✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.
