A population of rabbits oscillates 18 above and below average during the year, hitting the lowest value in January (t = 0). The average population starts at 650 rabbits and increases by 160 each year. Find an equation for the population, P, in terms of the months since January,
There are two functions here
trigonometric and exponential function
Trigonometric function:
we can use formula
we are given
A=-18
T=12
now, we can plug values
Exponential function:
we can use formula
a=650
at t=1, f(t)=650+160=810
we can plug it
now, we can find function
