Answer:
Option D. is the answer.
Step-by-step explanation:
Option A.
From the table we can see that for the value of x = 3, there are two values of y (14 and 19).
Which is not possible for a function. It should be one to one.
So option A is not a function.
Option B.
In this option again we have two values of y = 0, -5 for the value of x = 3.
For a function values of x and y should be one to one.
Therefore, it's not a function.
Option C.
Here for x = -1, there are two values of y (y = -11 and 5).
Therefore, it's not a function.
Option D.
In the given graph we find that there are different values of y for every value of x.
Therefore, Option D is the answer.
