Question

Does this graph represent a function? Why or why not?

Answer 1

No because it fails the vertical line test.

Answer 2

B. No, because it fails the vertical line test.

Explanation:

We know that,

'Vertical Line Test' states that 'If a vertical line which passes through the graph cuts the graph at most one point, then the graph represents a function'.

Since, from the given graph, we see that,

A vertical line like 'x= 8' is drawn, then it will pass through the graph at more than one point.

Thus, the graph fails the vertical line test.

So, it does not represent a function.
