This is a free lesson from our course in Algebra I
In this lesson, you'll learn how relations can have one to many mapping. You'll also learn how to determine whether two
sets of points have one to one mapping or many to one. As you might
already know, the points with same values of y for different values of x
have many to one mapping. For example, {(0, 5), (1, 5), (2, 5), (3, 5), (4, 5)}
has many to one mapping. However, if in a set of points each x has a unique
y for it, then it's a case of one to one mapping. A function which may (but does not necessarily) associate a given member of the range of with more than one member of the domain. (More text below video...)
People who saw this lesson also found the following lessons useful:
(Continued from above) For example, trigonometric functions such as sin x are many-to-one since sin x = sin(2p+x) = sin(4p+x)..

• Many to One relation:
As many of you know, Winpossible's online courses use a unique teaching method where
an instructor explains the concepts in any given area to you in his/her own voice
and handwriting, just like you see your teacher explain things to you on a blackboard
in your classroom. This particular lesson includes the teacher's instruction, practice
questions as well as end-of-lesson quizzes for practice. As we mentioned above,
you can
enroll in our online course in Algebra I by clicking here.
The format of Winpossible's online courses is also very suitable for teachers who
are using an interactive whiteboard such as Smartboard on Promethean in their classrooms,
because the course lessons can be easily displayed on such interactive whiteboards.
Volume pricing is available for schools interested in our online courses. For more
