Determine whether each of these functions is a bijection from R to R.

Solution:Step 1 ;We have to check weather the following function are bijection from .given functions are (a) Ans : first check f is one-one consider for all x,y this shows .’. f is one-one.Next check f is ontotake .’. and function g is .’. this is the inverse of f . it makes the g as a function.then it is onto,.’. the function is both one-one and onto Then f is bijective.
