In the year 2000, the pet population in Starkesville was measured to be 4,000. By 2010, the population had grown to 6,000. Assume the pet population continues to change linearly. If x represents the number of years since 2000, what equation could be used to predict the pet population in 2025?
a. P(x) = 400x + 2000 b. P(x) = 200x + 4000 c. P(x) = 2000x + 400 d. P(x) = 25x + 4000
