Write an exponential function that satisfies the given conditions:
- Initial mass: 1.3 g
- doubling every week

Answer:
1.3(2)^t
Step-by-step explanation:
1.3(2)^t
You start with 1.3 because that is your inital amount, then you multiply by 2 because it doubles, and your exponent will be t (the number of weeks)
