Let f be a twice-differentiable function. Which of the following statements are individually sufficient to conclude that x=2 is that location of the absolute maximum of f on the interval [-5, 5]?
l. f'\left(2\right)=0f′(2)=0
ll. x = 2 is the only critical pint of f on the interval [-5, 5], and f"\left(2\right)<0.f"(2)<0. lll. x = 2 is the only critical point of f on the interval [-5, 5], and f\left(-5\right) ll only l and ll only
lll only
ll and lll only
