Answer:
B - P=11.8(1.02)^t
Step-by-step explanation:
An exponential function is defined as:
[tex]y=ab^{x}[/tex].
Recall, a is the starting value, b is the rate, and x is the input (often time).
We will substitute a=11.8 million, b=1.02, and x=t for years. Notice b=1.02 and not 0.02. Because the population is increasing, we multiply by 1+r to add the growth onto the current population.
We write: [tex]y=11.8(1.02)^{t}[/tex] where y is population in millions.
