1) The dimensions of an irregular solid are as shown in the figure below. a) Write a polynomial function, in standard form, to model the volume of this solid. 3 x+ 2 3 2 x+ 1 x + 5 b) If the volume of the solid is 208 cubic inches , what is the value of x? I 2) The rational function shown could be used to the number of arrests, f(x) , per 100, 000 drivers, for driving under the influence of alcohol, as a function of a driver's age, x. f (x) = 27725(x-14) x2+9 - 5x a) Describe the trend you see in the graph, in context. b) Use a graphing utility to determine the age that corresponds to the greatest number of arrests
