Question Description

I’m working on a exercise and need support.

Describe the vertical-line test for functions.  Why is the vertical-line test a valid method for testing if a graph is a function or not.  (Hint: What is the connection between the vertical-line test and the definition of a function, i.e. what does a single vertical line represent, and how does this test if a graph is or is not a function?)
