A function f defined bya)an even functionb)an odd functionc)both even and odd functiond)neither even nor odd functionCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Sol:- Given f(x)=ln(√x^2+1-x)
now f(-x)=ln(√x^2+1+x)
so,f(x)=!f(-x)
It is odd function.

Answer

Hence it is an odd function.
