The cost for an upcoming field trip is $30 per student. The cost of the field trip \(C\), in dollars, is a function of the number of students \(x\).
Select all the possible outputs for the function defined by \(C(x)=30x\).
A rectangle has an area of 24 cm2. Function \(f\) gives the length of the rectangle, in centimeters, when the width is \(w\) cm.
Determine if each value, in centimeters, is a possible input of the function.
Select all the possible input-output pairs for the function \(y=x^3\).
A small bus charges $3.50 per person for a ride from the train station to a concert. The bus will run if at least 3 people take it, and it cannot fit more than 10 people.
Function \(B\) gives the amount of money that the bus operator earns when \(n\) people ride the bus.
- Identify all numbers that make sense as inputs and outputs for this function.
- Sketch a graph of \(B\).
Two functions are defined by the equations \(f(x)=5-0.2x\) and \(g(x)=0.2(x+5)\).
Select all statements that are true about the functions.

The graphs show the audience, in millions, of two TV shows as a function of the episode number.
For each show, pick two episode numbers between which the function has a negative average rate of change, if possible. Estimate the average rate of change, or explain why it is not possible.
