Number of Bijective Functions

Number of bijective function from a set of 10 elements to itself is

If f(1)+f(2)+f(3)=3 and A={0,1,2,3,. . . 9} , then find the number of bijective function f:A to A which satisfy?

A is a set having 6 distinct elements. The number of distinct functions from A to A which are not bijection is

A function is called one - one if each element of domain has a distinct image of co - domain or for any two or more the two elements of domain, function doesn't have same value. Otherwise function will be many - one. Function is called onto if co - domain = Range otherwise into. Function which is both one - one and onto, is called bijective. answer is defined only for bijective functions. Let f:[a, oo)rarr[1, oo) be defined as f(x)=2^(x(x-1)) be invertible, then the minimum value of a, is

Let n(A)=4,n(B)=4. Find number of possible bijective functions from A to B .

If f:A rarrB is bijective function such that n(A)=10, then n(B)=?

If f: A-> B and g: B-> C be the bijective function, then (gof)^(-1) is:

For the function f (x) = (x + 3)/( x - 5) to be a bijective function, the domain and range, respectively of f (x) must be :
