c. Write a function to represent the total number of pictures taken. Then
determine the number of pictures taken in 22 sessions.​

Answer 1

A)

• Independent variable -> number of sessions
• Dependent variable -> number of pictures

B)

Values of the domain that make sense would be those from 0 on because there are no negative number of sessions; values of range that make sense would be also those from 0 on because there are no negative number of pictures.

If we have 22 session then:

`f(22)=15*22`; f(22)=
`f(22)=330`
