MINI LESSON

Families of Functions

Different families of functions describe different patterns of change.

Linear functions change by a constant amount, quadratic functions involve squared terms and form parabolas, and exponential functions change by a constant percent or factor over equal intervals.

Question 1

On an island, a rare breed of rabbit doubled its population each month for two years. Which type of function best models the increase in population at the end of two years?
