function and not function graph example I ve learned that common examples of graphs that are not functions include those of ellipses and rectangles as these shapes fail the vertical line test at multiple points For instance with an ellipse which includes the special
When dealing with functions in math it is important to be able to recognize whether or not a given graph represents a function or not This short guide will explore and answer the questions When is a relation in the form y or f x a In this lesson you will further explore functions and non functions by examining their equations and graphs in greater detail You ll also consider the constraints on domain and range that are

If a vertical line drawn anywhere on the graph of a relation only intersects the graph at one point then that graph represents a function If a vertical line can intersect the graph at two or more points then the graph does Here s a brief list indicating non examples of functions A graph with any vertical line crossing it in more than one point A table or set of ordered pairs showing the same input x with different outputs y
Sketch x2 y2 16 and explain why it is not the graph of a function Solution x2 y2 16 is not a function as it fails the vertical line test For example when x 0 y 4 You ve had the opportunity to explore many examples of functions and non functions In the box below explain the difference between a function and a non function

It provides tables and graphs of relations that illustrate functions such as a y value being mapped to only one x value as well as non functions where a single x value is mapped to multiple y values or a y value is not How To Given a graph use the vertical line test to determine if the graph represents a function Inspect the graph to see if any vertical line drawn would intersect the curve more than once If
In this video we explore relations that are functions and relations that are not and how to tell whether or not they are functions Howto Given a graph of a function use the horizontal line test to determine if the graph represents a one to one function Inspect the graph to see if any horizontal line drawn would
