Number of Functions from Set A to Set B Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of Functions from A to B = (Number of Elements in Set B)^(Number of Elements in Set A)
NFunctions = (n(B))^(n(A))
This formula uses 3 Variables
Variables Used
Number of Functions from A to B - Number of Functions from A to B is the number of relations from Set A to Set B in which each element of A will be mapped with only one element in B.
Number of Elements in Set B - Number of Elements in Set B is the total count of elements present in the given finite set B.
Number of Elements in Set A - Number of Elements in Set A is the total count of elements present in the given finite set A.
STEP 1: Convert Input(s) to Base Unit
Number of Elements in Set B: 4 --> No Conversion Required
Number of Elements in Set A: 3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
NFunctions = (n(B))^(n(A)) --> (4)^(3)
Evaluating ... ...
NFunctions = 64
STEP 3: Convert Result to Output's Unit
64 --> No Conversion Required
FINAL ANSWER
64 <-- Number of Functions from A to B
(Calculation completed in 00.004 seconds)

Number of Relations from Set A to Set B which are not Functions
​ Go No. of Relations A to B which are not Functions = 2^(Number of Elements in Set A*Number of Elements in Set B)-(Number of Elements in Set B)^(Number of Elements in Set A)
Number of Injective (One to One) Functions from Set A to Set B
​ Go Number of Injective Functions from A to B = (Number of Elements in Set B!)/((Number of Elements in Set B-Number of Elements in Set A)!)
Number of Functions from Set A to Set B
​ Go Number of Functions from A to B = (Number of Elements in Set B)^(Number of Elements in Set A)
Number of Bijective Functions from Set A to Set B
​ Go Number of Bijective Functions from A to B = Number of Elements in Set A!

Number of Functions from Set A to Set B Formula

Number of Functions from A to B = (Number of Elements in Set B)^(Number of Elements in Set A)
NFunctions = (n(B))^(n(A))

What is a Function?

A Function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).
