Suppose a gauge at the outflow of a reservoir measures the flow rate of water in units of ftcubed/hr. The total amount of water that flows out of the reservoir is the area under the flow rate curve. Consider the flow rate function shown in the figure to the right. Complete parts (a) through (d) below. Does more water flow out of the reservoir over the interval [0,4] or [4,6]? 1500 ft cubed more water flows out of the reservoir over the interval 4 comma 6. (Simplify your answers. Type integers or decimals.)
