Let f(x)=(f(x))^(2)+(f'(x))^(2),F(0)=0 where f(x) is thrice differentiable function such that |f(x)|le1 for all x in [-1, 1], then choose the correct statement(s)

Answer»

There is atleast and point in each of the intervals `(-1, 0)` and (0, 1)where `|f'(x)|le 2`
There is atleast one point in each of the intervals `(-1, 0)` and 0, 1) where `F(x)le5`
There is no point of local maxima of F(x) in `(-1, 1)`
For some `c in (-1, 1), F(c)GE 6, F'(c) =0 and F''(c) LE0`
