Final answer:
a) Exponential growth. The function P = P0e^1.41t represents exponential growth.
Step-by-step explanation:
The function P = P0e^t represents exponential growth if the value of t is positive and exponential decay if the value of t is negative.
In the given function P = P0e^1.41t, the value of 1.41t is positive. Therefore, this function represents exponential growth.
