SYNTHESIS We have now studied models for linear, quadratic, exponen- tial, and logistic growth. In the real world, understanding which is the most appropriate type of model for a given situa- tion is an important skill. For each situation in Exercises 50-60, identify the most appropriate type of model and explain why you chose that model. List any restrictions you would place on the domain of the function 52. The growth in sales of electric cars 53. The drop and rise of a lake's water level during and after a drought 54. The rapidly growing sales of organic foods 55.
