A function that is both one-to-one and onto is called bijective or a bijection. If f maps from A to B then f-1 maps from B to A. Suppose that A and B are

Function - Purdue University

a function that is strictly increasing or strictly decreasing throughout its domain is one-to-one (no turning points) all linear functions are one-to-one because they are either always increasing or always decreasing the graph of a quadratic function is parabola which is both increasing and decreasing so it is not one-to-one

A function is said to be one-to-one provided that the following holds for all x 1 and x 2 in the domain of f : If f x f x then xx Use the above definition to determine whether or not the following functions are one -to-one If f is not one-to-one then give a specific example showing that the condition 12 xxf x f x fails to imply that 12 59

Constructing an onto function from A to B is only possible when A has at least as many elements as B Constructing a one-to-one function from A to B requires that B have at least as many values as A So if there is a bijection between A and B then the two sets must contain the same number of elements

What test determines if a function is one to one?

Using the Horizontal Line Test. An easy way to determine whether a function is a one-to-one function is to use the horizontal line test on the graph of the function. To do this, draw horizontal lines through the graph. If any horizontal line intersects the graph more than once, then the graph does not represent a one-to-one function.

Is absolute value an one to one function?

Absolute value graph: The graph of the function,[latex]f(x)=left | x right |latex], fails the horizontal line test and is therefore not a one-to-one function. Symmetry of Functions Two objects have symmetry if one object can be obtained from the other by a transformation.
