Six guinea pigs are released in an area with no natural predators. The guinea pig population quadruples every year. Write a function p that represents the guinea pig population at a given time t measured in years

SOLUTION:
Case: Exponential equation
Method:
Initial population: 6
Quadruple each year, multiplier= 4.
Where t is the number of years, the population is:
[tex]P=6(4)^t[/tex]a) The inverse is calculated as:
[tex]\begin{gathered} \frac{P}{6}=4^t \\ log(\frac{P}{6})=log4^t \\ log(\frac{P}{6})=tlog4^ \\ t=\frac{log(\frac{P}{6})}{log(4)} \\ P^{-1}=\frac{log(\frac{t}{6})}{log(4)} \end{gathered}[/tex]b) Approximately how long to reach 1000 guinea pigs
[tex]\begin{gathered} P^{-1}=\frac{log(\frac{1000}{6})}{log(4)} \\ P^{-1}=3.69 \end{gathered}[/tex]Final answers:
a)
[tex]P^{-1}=\frac{log(\frac{t}{6})}{log(4)}[/tex]b)
[tex]P^{-1}\approx3.7[/tex]
