Question:

The amount spent by international visitors to the United States during the years 1990 through 2016 can be modeled by the polynomial function P(x) = 0.01287x³ - 0.3514x² + 4.979x + 45.24, where x = 0 represents 1990, x = 1 represents 1991, and so on, and P(x) is in billions of dollars. Use this function to approximate the amount spent by international visitors to the United States (to the nearest tenth) in each given year.

(a) 1990

(b) 2005
