Question

2. Which relation below is NOT a function?

Answer 1

Answer:

b

Step-by-step explanation:

The answer is B because different X values cannot have the same y values. For example in A the x values, -2 and 0, have the same y value 4. That's not possible.

Although C also has a similar problem ALL of the X values have the same y value meaning that the function is an undefined function which is still a type of function. Its basically a function where all the y values are the same.

Answer 2

C is the answer to that question i think
