The giant panda population in China is increasing at a rate of 1.5% each year. There are 1864 giant panda in 2014. Write a function that models the panda population since 2014.

(exponential growth & decay)

Given:

Giant panda population in 2014 = 1864

The giant panda population in China is increasing at a rate of 1.5% each year.

To find:

The function that models the panda population since 2014.

Solution:

Since population of giant panda is increasing, therefore the function is the exponential growth model.

The general exponential growth model is:

[tex]P(t)=P_0(1+r)^t[/tex]

Where, [tex]P_0[/tex] is the initial population, r is the growth rate in decimal and t is the time period.

Putting [tex]P_0=1864,r=0.015[/tex], we get

[tex]P(t)=1864(1+0.015)^t[/tex]

[tex]P(t)=1864(1.015)^t[/tex]

Where, t is the number of years since 2014.

Therefore, the required exponential growth model is [tex]P(t)=1864(1.015)^t[/tex].
