Hi, I'm a college student with an college level Intermediate Algebra question: Which are the following are not functions?
Your help is greatly appreciated.
Thank you, Hi Christian, Try graphing these relations and applying the vertical line test. Imagine a series of vertical lines superimposed over the graphs. If any of these vertical lines goes through the graph more than once, it is not a function. If each vertical line goes through the graph at most once, it is a function. Hope this helps, Leeanne
