Need solution for RD Sharma maths class 12 chapter Functions exercise 2.1 question 8 sub question (ii)
f is not bijective
, given by
Function f is one-one, onto or bijective.
For any function to be a 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 one-one function
So, g is not 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; , there is no value of x inA
Hence, f is not onto.
So, g is not onto.
Hence g is not bijective.
