Suppose you are studying the graph of a population of a particular species and you determine that the tangent line at t = 3 is given by y = 19 - 4t. Assuming that the tangent - line provides a good approximation to the population of the species near t = 3, which of the following should hold? The population at t = 2.9 is less than than the а) population at t = 3, and the population at t = 3.1 is less than than the population at t = 3. The population at t = 3 is less than than the b) population at t = 3.1, and the population at t = 2.9 is less than than the population at t = 3. The population at t = 3 is less than than the population at t = 2.9, and the population at t = 3.1 is less than than the population at t = 3.
