Understanding Functions and Their Representations

What are the different ways to represent functions as mentioned in the introduction?

• Words and tables only

• Graphs and tables only

• Only equations and graphs

• Words, equations, tables, and graphs

If a drama club sells pies at $5 each, what equation represents the total earnings for P pies?

• t = P - 5

• t = 5 * P

• t = P / 5

• t = 5 + P

How would you express the total number of breaths taken in m minutes if the rate is 14 breaths per minute?

• b = 14 - m

• b = m / 14

• b = 14 * m

• b = 14 + m

What equation represents the distance a mouse can travel in h hours if it travels at 8 miles per hour?

• d = 8 + h

• d = 8 * h

• d = h / 8

• d = 8 - h

If Samantha makes 36 cookies per hour, what equation represents the total cookies made in H hours?

• C = 36 + H

• C = 36 * H

• C = H / 36

• C = 36 - H

In the car wash example, what is the equation for the total earnings T for washing C cars?

• T = 7 * C

• T = 7 - C

• T = 7 + C

• T = C / 7

What is the independent variable in the car wash function graph?

• Total earnings

• Number of cars washed

• Time taken

• Cost per car

In the bald eagle flight example, what is the equation for the total distance d traveled in h hours?

• d = h / 30

• d = 30 + h

• d = 30 - h

• d = 30 * h

What is the dependent variable in the bald eagle flight function graph?

• Altitude of flight

• Time of flight

• Speed of the eagle

• Total distance traveled

How does the distance change in the bald eagle flight graph?

• Fluctuates randomly

• Remains constant

• Increases by 30 miles every hour

• Decreases by 30 miles every hour
