Understanding Exponential Functions in Fines

The video tutorial explains how Sarah Swift's speeding ticket fine is calculated using an exponential function. It covers the concept of exponential functions, the calculation of the common ratio, and the derivation of the function formula. The tutorial also demonstrates how to calculate the fine if Sarah pays on time, emphasizing the importance of understanding exponential growth in real-world scenarios.

What happens if Sarah Swift delays her payment for the speeding ticket?

• She receives a discount.

• There is no change in the fine.

• A penalty is added based on the delay.

• The fine is canceled.

What type of function is used to represent the fines for Sarah's speeding ticket?

• Logarithmic function

• Exponential function

• Quadratic function

• Linear function

What is the common ratio in the exponential function for Sarah's fines?

• 1.2

• 1.5

• 0.5

• 2.0

How is the common ratio determined in the context of Sarah's fines?

• By adding consecutive fines

• By multiplying consecutive fines

• By dividing consecutive fines

• By subtracting consecutive fines

What is the formula for the exponential function representing Sarah's fines?

• f(t) = 300 * 1.5^t

• f(t) = 200 * 1.5^t

• f(t) = 200 * 2^t

• f(t) = 300 * 2^t

• 200 euros

• 675 euros

What does 't' represent in the formula for Sarah's fines?

• The penalty rate

• The initial fine amount

• The number of months payment is delayed

• The total fine amount

How does the fine change if Sarah delays her payment by one month?

• It decreases by a factor of 1.5

• It remains the same

• It increases by a factor of 1.5

• It doubles

What mathematical operation is used to calculate the fine for each additional month of delay?

• Addition

• Division

• Multiplication
