Need solution for RD Sharma maths class 12 chapter Functions exercise 2.1 question 8 sub question (iii)
f is not bijective.
, given by
Function h is one-one, onto or bijective.
For any function to be bijective, the given function should be one-one and onto.
First we will check whether the given function is one-one or not.
We know for function h to be one-one
Let such that
Hence, the value of y is defined only if y is positive,
But y is a real number
Hence, if y is negative, there is not corresponding element of x
i.e; for , there is no value of x in A.
Hence, h is not onto.
Hence, h is not bijective.
