Question

Which values of x, if any, prove that the graph below is not a function?

Answer 1

3

Explanation:

For a graph not to be a function, it means that a particular value of x has more than one corresponding value of y. Looking at the graph, at the point where x = 3 on the horizontal axis, there are so many value of y. Plus, the graph below is not a function at x = 3

The correct option is 3
