Exploring Exponential Growth and Decay Concepts

The video tutorial introduces students to exponential growth and decay, explaining how to analyze scenarios and determine if they represent growth or decay. It covers the equations used for both processes, emphasizing the importance of converting percentages to decimals. Real-world examples, such as population growth and car depreciation, are used to illustrate these concepts. The lesson concludes with instructions for completing assignments on Google Slides.

What does the 'a' in the exponential growth and decay equation represent?

• The variable exponent

• The y-intercept or initial value

• The percentage rate

• The common ratio

For exponential growth, the 'B' value must be:

• Less than 1

• Exactly 1

• Greater than 1

• A negative number

In the population growth example, what is the initial population size?

• 400,000

• 100,000

• 200,000

• 300,000

How is the growth rate of 5% converted for the equation?

• 0.05

• 105

• 5

• 1.05

What is the correct way to convert a percentage to a decimal for the equation?

• Divide by 100

• Multiply by 100

• Add 1 to the percentage

• Subtract the percentage from 100

For exponential decay, the 'B' value must be:

• Greater than 1

• Less than 0

• Between 0 and 1

• Exactly 1

What does depreciation mean in the context of exponential decay?

• Conversion to percentage

• Stable value

• Decrease in value

• Increase in value

In the car depreciation example, what is the initial value of the car?

• $15,000

• $16,000

• $17,000

• $18,000

After depreciation, what is the 'B' value for the car's value each year?

• 0.2

• 0.5

• 0.8

• 1.2
