Problema Solution

the population density of a certain animal has been found to be decaying over several years. The population can be modeled by the function p(x)=7.8(.975)^x where x is the number of years after 1900

Is the population decaying exponentially or linearly? Explain your determination. What will the population be in 10 years?

Answer provided by our tutors

p(x)=7.8(.975)^x.

 

The population is decaying exponentially. Because the function varies as the power of x.

After 10 years : P(10) = 6.055
