Question

in 2000 the world's population was 6.08 billion and was increasing at a rate of 1.21% each year. write a function for world population does the function represent growth or decay.

Answer 1

The correct function in the problem is A= 6.08*e^(.0121*t). This equation was derived from the basic growth function which is A= Pe^(r∗t). The initial amount, which is 6.08 billion, is substituted in P. Letter 'e' stands for the constant 'e' from the calculator.
