Question

True or false? The graph represents a function

Answer 1

The statement is false because if the red line had a vertical line going through it the line would hit it twice as shown in the picture below

Answer 2

False. This is not a function.

Explanation:

By using the vertical line test, it shows that this graph is not a function. The imaginary vertical line would go through the graph twice. To be a function, the imaginary vertical line can only go through once.
