The opening value of a stock index on the first day of trading from 1994 to 2010, can be modeled using the following polynomial: N(t) = 5.95t + 10.15t + 11t + 400, where t is time in years since 1994. A) Graph this function in an appropriate window for years 1994-2010, label completely. B) What is the vertical intercept (y-intercept), and what does this tell you in practical terms? C) Based on this model, what was the opening value stock index on the first day of trading in 2005?
