Let f((x))2 + (f( f(0) = 6 where f(x) is a thrice differentiable function such that if(x)i 1 x e [-1, 1] , then choose the correct statement(s) (a) there is at least one point in each of the intervals (-1, 0) and (0, 1) where if'(x)) s 2 (b) there is at least one point in each of the intervals (-1, 0) and (0, 1) where f(x) (c) there is no point of local maxima of f(x) in (1, 1) (d) for some c e (-1, 1), f(c) 26, f(c) 0 and f"(c) s 0 x.
