Ascientist is studying the change in population for two species of fish in a lake. the table shows how the numbers of each species changed during a 4-year period. the scientist uses a linear model to predict future populations of both fish. explain why, given the data in the table, the population of fish a and the population of fish b can be modeled using linear equations. b. based on the data, which fish population is changing at the greatest rate? explain your answer. c. write an equation in form using the data in the table for the population of fish a and fish b. let x represent the year and y represent the fish population. d. the scientist studies a third population of fish in the lake, fish c. the data for fish c cannot be modeled with a linear equation. find the missing values in the table below to show data that represents a non-linear model for the change in population. explain your answer.
