ãä¸å½çµ pt) decreases on function is increasing on an open interval and an endpoint of the interval is in the domain INCLUDES the endpoint. For example, if f is increasing on (1,2) and 1 and 2 are in the domain of f, then it is better to say that f is increasing of the function, then it is preferable to say that the interval where the no local Local maxima occur at r - Local minima occur at = of a given type, enter 'none than one give a list. If there are no local extrema of a given type, enter 'none and the points at which the function attains
