In each paragraph 2 multiple choice questions have to be answered. Each question has four choices (A), (B), (C) and (D) out of which ONLY ONE is correct.
Let f(x)=(1+x)2sin2x+x2 for all x ϵ IR, and let g(x) =
Consider the statements:
P :There exists some xϵ IR such that f(x)+2x=2(1+x2)
Q :There exists some xϵ IR such that 2f(x)+1=2x(1+x) Then
