A rabbit population can increase at a rapid rate if left unchecked. Assume that 10 rabbits are put in an enclosed wildlife ranch and the rabbit population triples each year for the next 5 years as shown in the table. 0 -> 10

1 - > 30

2 -> 90

3 -> 270

4 -> 810

5 -> 2,430

Part A: Let y represent the number of rabbits after x years. Build a function rule that can be used to model y as a function of x, where x is a non-negative number.
