The total number of a particular chain store in the world can be modeled by the cubic function y = 10.3x-396x+5592x-8691, where x is the number of years after 2000 and y is the tota number of stores. Complete parts (a) through (c) below. (a) Graph the function on the window [2,20,2] by [8000,23000,1000]. OB. G (b) What does the model predict the number of stores will be in 2020? The model predicts that there will be stores in 2020. (Round to the nearest whole number as needed.) G C. G D. Q Q G
