A certain town is experiencing a population boom. In 1990, the population was 890 and five years later it was 1210. (a) Find a linear model /(x) for the population of the town in the year 1990 + x. 1(x)= Find an exponential model p(x) for the population of the town in the year 1990 + x. (Round values to three decimal places.) p(x) = (b) What do these models estimate the population of the town to be in the year 2000? (Round your answers to the nearest whole number.) (2000) = P(2000) = people people
