Problem 23E

Determine whether each of these functions is a bijection from R to R Step-by-Step Solution:

Step 1 :

We have to check weather the following function are bijection from .

given functions are

(a) Ans :

First check the given function is one-one Such that .’. The given function is one-one.

next we to check the onto

In the given function the range is real numbers .’. The function is onto

Hence the function is bijective.

Step 2 :

(b) Ans :First check the given function is one-one

consider we can have the same values of even the different values of x,

.’. the function is not one one

Hence the function is not bijective.
