Exponential Functions: Growth and Decay

The video tutorial explains exponential functions, focusing on growth and decay factors and rates. It provides examples to illustrate exponential growth and decay, showing how to calculate growth and decay rates. The tutorial also covers more complex scenarios, such as when the exponent is multiplied by a constant. The video aims to clarify the differences between growth factors and rates, as well as decay factors and rates, providing a comprehensive understanding of exponential functions.

What is the condition for an exponential function to represent growth?

• The base B is greater than 1.

• The base B is equal to 1.

• The base B is less than 1.

• The base B is negative.

In an exponential function, what does the variable 'r' represent when it is greater than zero?

• Growth factor

• Decay factor

• Growth rate

• Decay rate

In the example y = 100 * 1.17^t, what is the growth rate?

• 1.17

• 17%

• 7%

What is the initial amount in the function y = 500 * 0.76^t?

• 76

• 0.76

• 1.76

• 500

In the function y = 500 * 0.76^t, what is the decay factor?

• 0.76

• 1.76

• 24%

• 0.24

What is the decay rate in the function y = 500 * 0.76^t?

• 24%

• 0.76

• 76%

• 0.24

In the function y = 800 * 0.96^(3t), what is the transformed base after simplifying?

• 0.736

• 0.96

• 1.736

• 0.8847

What is the decay rate in the function y = 800 * 0.96^(3t) after simplification?

• 5.26%

• 8.84%

• 11.52%

What is the difference between a growth factor and a growth rate?

• Growth factor is a percentage, growth rate is a decimal.

• Growth factor is always less than 1, growth rate is always greater than 1.

• Growth factor is a decimal, growth rate is a percentage.

• Growth factor is always greater than 1, growth rate is always less than 1.
