Answer:
Option (A)
Step-by-step explanation:
If 'x' value (input value) of a function has two y-values (output values) then the representation will be a relation not a function.
Option (A).
In the option every value of x has different output value (y-value).
Therefore, Option (A) represents a function.
Option (B).
Input value x = 0 has two output values y = 0, 12
Therefore, given representation is not a function.
Option (C).
From the table attached,
Input value, x= -1 has four output values (y = 0, 5, 10, 15)
Therefore, table doesn't represent a function.
Option (D).
In the given table x = -4 has two output values y = -8 and 10.
Therefore, table doesn't represent a function.
