Identification of Function
Function is classified as a special type of relation in math. There are following rules which can be used to identify a function:
- A relation in which each input mapped to a unique output is a Function. This called one to one function.
- A relation in which two input(preimage) mapped to a single output is also a Function. This is many to one function.
- A relation in which one input is mapped two different output is not a function.
- A relation in which many inputs are mapped to many outputs following no specific rule is not a function.
What is a Function in Maths?
A Function in maths is a special relation between the set of input values and the set of output values. In Function, each input value gives a particular output value. We represent a function in maths as, y = f(x) where x is the input value and for each x we get an output value as y.
In this article, we will learn about, functions in mathematics, their various types, examples, and others in detail.
