Unformatted text preview: the tank t hours after the tank begins to ll is given by V t = t + t . Approximate the instantaneous rate at which water is entering the tank one hour after the tank begins to ll. Explain clearly how you arrive at your approximation. You may not use derivatives! For problems and , evaluate each limit or explain clearly why it does not exist. . lim x ! x ; x ; . lim x !; x x + + x + . True or false? Justify your answers. a If lim x ! c f x + g x exists,but lim x ! c g x does not exist, then lim x ! c f x does not exist. b If lim x ! c f x exists, then lim x ! c f x exists....
