Answer: B The starting population
Steptostepexplanation:
Given: The frog population at a lake doubles every three weeks. The population can be modeled by [tex]f(x)=15(2)^x[/tex] and [tex]f(6)=960[/tex]
The given function is a exponential growth function in which the independent variable (x) appears in exponents and with constant multiplicative rate of change .
When we substitute x=0 in the given function, we get
[tex]f(0)=15(2)^0=15\times1=15[/tex]
Hence, 15 represents the starting population .
