The projected worldwide spending for a certain type of service, in millions of dollars, for the years 2006-2011 can be estimated by the polynomial s= -35.4x² +924.6x +493, where x is the number of years after 2006. Find the projected worldwide spending for x=0, x=2, and x = 5. Use the polynomial to estimate the projected worldwide spending for this service, in millions of dollars, for the year 2006 (x = 0). $million (Type an integer or a decimal.)
