Many public entities like cities, counties, states, utilities, and Indian tribes are hiring firms to lobby Congress. One goal of such lobbying is to place earmarks-money directed at a specific project-into appropriation bills. The amount (in millions of dollars) spent by certain public entities on lobbying in a theoretical six-year span is given by f(t) = -0.375t³ + 5.832t2 +9.039t + 43.7 (0 ≤ts 6) where t is measured in years, with t = 0 corresponding to the first year. (a) Is fincreasing or decreasing on (0, 6)? O increasing O decreasing O varies (b) Find the inflection point of f. (Round your answer to two decimal places.) t =
