IT is b because you cant repeat a number in the (x) for it to be a function. 2 is repeated.

Answer:

Option B is correct! Because for the x=2, there are two y values. Below is a detailed explanation.

Step-by-step explanation:

Function:

    A function does not have two different outputs(y) for the same input(x).

Let's analyze each option.

For option A:

 The x values are {0,2,4,-2,5}

Here none of the x values are repeated.

So, it represents a function.

For option B:

   The x values are {0,2,4,2,5,7}

Here the x value '2' is repeated two times.

According to the explanation of the function, when x=2, the 'y' can not be equal to 2, 7.

So, this is not a function.
