Can you help me with my calculus?

The graph shows the depth of water W in a reservoir oyera one-year period as a function of the number of days xsince the beginning of the year. [Assume 355 clays in a year.) W01) [00 75 5t] 25 0 mo zuc- 300 \"dam (a) Determine the intervals on which the function W is increasing. (Select all that apply.) D (a, 150) D [150. 300] D (300. 355] Determine the intervals on which the Function W is decreasing. {Select all that apply.) D (a. 150) C] (150, 300] D (300. 355] (b) At What value of x clues W achieve a local maximum? clays At what value otx does W achieve a local minimum? clays (c) Find the net change in the depth W from 100 days to 300 clays. :IFt Three runners compete in a lDCl-meter hurdle lace. The glaph depicts the distance run as a function of time for each runner. Describe in words what the graph tells you about this race. r (m) 100 Who won the race? 0 Runner A O Runner B O Runner C Did each runner finish the lace? 0 Yes ONO what do you think happened to Runner B? O Runner B fell. but got up and finished the lace. O Runner B an the first part 0F the race, walked during the mid-ElleJ then van the last part 0F the race. 0 Runner B stopped running and walked the rest: of the lace. O Runner B stumbled at the start at the race and began after the other two n.lnners. O Runner B increased speed the rst part of the racer Ian at a constant speed during the middle of the lace. then increased speed the last part of the race. The graph of a function is given. Use the graph to estimate the following. y X (a) All the local maximum and minimum values of the function and the value of x at which each occurs. local maximum (x, y) = (smaller x-value) local maximum (x, y) = (larger x-value) local minimum (x, y ) = (smaller x-value) local minimum (x, y) = (larger x-value) (b) The intervals on which the function is increasing and on which the function is decreasing. (Enter your answers using interval notation.) increasing decreasing
