# The u S population in 1910 was 92 million people. In 1990 the population was 250 million. How do you use the information to create both a linear and an exponential model of the population?

##### 1 Answer

Please see below.

#### Explanation:

The **linear model** means that there is a uniform increase and in this case of US population from

This means an increase of

graph{1.975(x-1910)+92 [1890, 2000, 85, 260]}

The **exponential model** means that there is a uniform proportional increase i.e. say

This means an increase of

This can be graphed as an exponential function

graph{92(1.0125743^(x-1910)) [1900, 2000, 85, 260]}
