Question

20. A photographer takes an average of 15 pictures per session. The total

Answer 1

Answer:

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.

C)

$f(x)=15x$, where "x" is the number of sessions.

If we have 22 session then:

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