One One and Onto functions (Bijective functions)

Last updated at Dec. 16, 2024 by

One-one is also known as injective.

Onto is also known as surjective.

 

Both  one-one and onto are known as bijective .

 

Check whether the following are bijective.

Example 1 - Checking one one and onto.jpg

Function is one one and onto.

∴ It is bijective

One One and Onto functions (Bijective functions) - Part 2

Function is one one and onto.

∴ It is bijective

One One and Onto functions (Bijective functions) - Part 3

Function is not one one and not onto.

∴ It is not bijective

One One and Onto functions (Bijective functions) - Part 4

Function is one one but not onto.

∴ It is not bijective
