A city had a population of 40,000 people in the year 2010. The table models the population, y, after a given number of years, x. x (years) 0 1 2 3 4 y (population) 40,000 48,000 57,600 69,120 82,944 Which type of model would best fit the data, and why? Exponential growth, because the population is increasing by 20% each year Exponential decay, because the population is decreasing by 20% each year Linear, because the population is increasing by 20% each year Linear, because the population is decreasing by 20% each year
