Understanding Function Values

This video tutorial explains the concept of function values through two examples. The first example interprets the cost function for producing gallons of chocolate chunk ice cream, while the second example deals with the average credit card debt in U.S. households. The video emphasizes understanding inputs and outputs in function values and performing necessary calculations to interpret real-world scenarios.

What does the function c(g) represent in the context of the video?

• The total sales of chocolate chunk ice cream.

• The number of gallons of chocolate chunk ice cream produced.

• The cost to produce a certain number of gallons of chocolate chunk ice cream.

• The profit from selling chocolate chunk ice cream.

In the function c(763) = 147, what does the number 763 represent?

• The year of production.

• The number of gallons of ice cream.

• The cost in dollars.

• The profit margin.

What is the output of the function c(763) = 147?

• The number of gallons produced.

• The year of production.

• The cost in dollars.

• The profit margin.

What does the function d(t) approximate?

• The number of credit cards in a U.S. household.

• The total savings of a U.S. household.

• The total average credit card debt in a U.S. household.

• The total income of a U.S. household.

In the function d(27) = 18.9, what does the number 27 represent?

• The number of credit cards.

• The number of years after 1995.

• The average income.

• The total debt in dollars.

What is the output of the function d(27) = 18.9?

• The number of credit cards.

• The average income in thousands of dollars.

• The total debt in thousands of dollars.

• The number of years after 1995.

How do you calculate the actual year from the input t in the function d(t)?

• Subtract t from 1995.

• Add t to 1995.

• Multiply t by 1995.

• Divide t by 1995.

What is the actual year when t equals 27 in the function d(t)?

• 2020

• 2022

• 2021

• 2023

How do you convert the function value 18.9 in d(27) = 18.9 to actual dollars?

• Subtract 1000.

• Add 1000.

• Divide by 1000.

• Multiply by 1000.

What is the total average credit card debt in a U.S. household in 2022 according to the function d(t)?

• $17,900

• $19,000

• $18,000

• $18,900
