All onto functions are one-one functions

All one-one function are onto functions

Examine whether the following functions are one-one and onto : f : N rarrN,f(x)=2x for all x in N

Examine whether the following functions are one-one and onto : f : R rarrR,f(x)=x^2 for all x in R

Examine whether the following functions are one-one, many-one or into, onto f(x)=x^(2)+lnx

Let f: R-{n}->R be a function defined by f(x)=(x-m)/(x-n) such that m!=n 1) f is one one into function2) f is one one onto function3) f is many one into funciton4) f is many one onto function then

Let f: R-{n}->R be a function defined by f(x)=(x-m)/(x-n) such that m!=n 1) f is one one into function2) f is one one onto function3) f is many one into funciton4) f is many one onto funcionn then

If (x)=|x-1|+|x-2|+|x-3|,f=[2,3]rarr R is (A) one-one,onto (B) an onto only (C) an identity function (D) an into function only

A bijection function is both one-one and onto?.

Let S be the set of all function from the set {1, 2, …, 10} to itself. One function is selected from S, the probability that the selected function is one-one onto is :
