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

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

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

Let f:NtoN defined by : f(n)={:{((n+1)/(2) "if n is odd"),((n)/(2) "if n is even"):}

If f: N rarr Z is defined by f(n) ={{:((n-1)/(2),"when n is odd"),(-n/2,"when n is even"):} then identify the type of function

Let f:N rarr N defined by f(n)={{:((n+1)/(2) " if n is odd"),(n/2" if n is even"):} then f is

The function f:NrarrZ defined by f(n)=(n-1)/(2) when n is odd and f(n)=(-n)/(2) when n is even, is

A function f from the set of natural numbers to integers is defined by n when n is odd f(n)3, when n is even Then f is (b) one-one but not onto a) neither one-one nor onto (c) onto but not one-one (d) one-one and onto both
