Compare the two functions described below.

function 1: originally there were 40 people living at schondel city. the city’s population is growing and the amount of people living in the city triples daily!

function 2: y = 15 • 0.8^x

Function 1 is modeled by the equation: 
y = 40 + 3x
where x is the number of days and y is the city's population or amount of people living in the city.
This is a linear equation because all of the terms have exponent 1.

Function 2 is a non-linear equation. Specifically, it is an example of an exponential equation because its variable x is found in the exponent. 

The length of what is left would be 1 1/2 feet long.
