Exponential functions

The standard exponential equation is expressed as;

y = ab^x

where

• a is the intercept
• b is the initial population
• x is the time

Given the following parameters

• a = 2000
• b = 0.02

Substittute the given parameters into the formula

y = 2000(1.02)^x

If x = 20 (from 2000 to 2020)

The population will be expressed as;

y = 2000(1.02)^20

y = 2972 populations

Hence the population will be about 2972 population in 2020
