Algebra 1 Section 8.5 Apply Exponential Functions When a quantity grows by the same amount each day it is experiencing linear growth. y = mx + b When a quantity grows by the same percent each day, it is experiencing exponential growth.

An exponential function takes the form y = C(1 + r) t C is the initial amount r is the growth rate t is the time period 1+r is the growth factor You deposit $600 in an account that pays 4% annual interest. What is the account balance after 6 years?

y = C(1 + r) t A population of 30 turkeys are released in a wildlife area with no turkeys. The population grows at a rate of 15% per year. How many turkeys will there be in 8 years?
