Give the correct order of initials T or F for following statements. Use T if statement is true and F if it is false.
Statement-1: If f : R → R and c ∈ R is such that f is increasing in (c – δ, c) and f is decreasing in (c, c + δ) then f has a local maximum at c. Where δ is a sufficiently small positive quantity.
Statement-2 : Let f : (a, b) → R, c ∈ (a, b). Then f can not have both a local maximum and a point of inflection at x = c.
Statement-3 : The function f (x) = x2 | x | is twice differentiable at x = 0.
Statement-4 : Let f : [c – 1, c + 1] → [a, b] be bijective map such that f is differentiable at c then f–1 is also differentiable at f (c).
