# Question #faf22

##### 1 Answer

The given function is linear, and it can also be expressed as

#### Explanation:

The given function is linear because the starting value is being added and the common difference is being multiplied.

There are two functions; linear and exponential. A linear function is one that has a common difference (which means it is being added or subtracted), and on a graph it will be a straight line.

An exponential function, however, is one that has a common ratio (which means it is being multiplied), and on a graph it will be a curved line.

The function notation for a linear equation is

while the exponential equation would be

In this problem, the starting value,

It is technically already in the form
