Let f be a function from the set of natural numbers to the set of even natural numbers given by f(x)=2x. Then f is

f: N to A where N is the set of natural numbers and A is the set of even natural numbers, defined by f(x) = 2x , then f is:

A function f from the set of natural numbers N to the set of integers Z is defined by f(n)={((n-1)/(2),"when n is odd"),(-(n)/(2),"when n is even"):} Then f(n) is -

A ={set of odd natural numbers}, B={sets of even natural numbers}, then A and B are

Let NN be the set of natural numbers and D be the set of odd natural numbers. Then show that the mapping f:NN rarr D , defined by f(x)=2x-1, for all x in NN is a surjection.

The function f:NtoN,N being the set of of natural numbers, defined by f(x)=2x+3 is

Let f be a function from C (set of all complex numbers) to itself given by f(x)=x^3 . Write f^(-1)(1) .

Let f be a function from C (set of all complex numbers) to itself given by f(x)=x^3 . Write f^(-1)(1) .
