Algebra I: Types of functions
This is a free lesson from our course in Algebra I
It covers another aspect of a function which is called one to one mapping. Overall, a function has one to one mapping if for every value of x there is one and only one value of y. For example, 2y + 3x = 6 is a function. A function has many to one mapping if more than one values of x equal to the same value of y. For example, y = f(x) = x2. The lesson will also show you the graphical representation and tabular representation of one to one mapping and many to one mapping with the help of examples.
