2. Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros. o g(x) = x3 − x2 − 4x + 4
o g(x) = x3 + 2x2 − 9x − 18
o g(x) = x3 − 3x2 − 4x + 12
o g(x) = x3 + 2x2 − 25x − 50
o g(x) = 2x3 + 14x2 − 2x − 14

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers. a) one of the 400 passengers is selected uniformly at random. let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem
