The number of U.S. travelers to other countries during the period from 1990 through 2009 can be modeled by the polynomial function P(x)= - 0.00540x +0.1149x + 1.095x+ 43.31 where x= 0 represents 1990, x= 1 represents 1991, and so on and P(x) is in millions. Use this function to approximate the number of U.S. travelers to other countries in each given year. (a) 1990 (b) 2000 (c) 2009 (a) In 1990, the number of U.S. travelers to other countries was approximately| (Simplify your answer.
