Question

Which representation shows y as a function of x?​

Answer 1

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.
