Introduction

The year 2000 marked a significant turning point in the history of home entertainment. The popularity of DVDs began to rise, and the number of VHS movie rentals started to decline. In this article, we will explore the mathematical model that describes this decline, using an exponential regression equation.

The Exponential Regression Equation

The exponential regression equation for the number of VHS movie rentals is given by:

$$y = 9.92(0.8209)^x$$

where $x$ represents the year, and $y$ represents the number of VHS movie rentals.

Understanding the Equation

The equation is an exponential function, where the base is 0.8209. This means that for every year that passes, the number of VHS movie rentals decreases by a factor of 0.8209. In other words, the number of VHS movie rentals is decreasing at an exponential rate.

Interpreting the Coefficients

The coefficient 9.92 represents the initial number of VHS movie rentals in the year 2000. This is the starting point for the exponential decline.

The coefficient 0.8209 represents the rate of decline. This value is less than 1, indicating that the number of VHS movie rentals is decreasing over time.

Graphing the Equation

To visualize the decline in VHS movie rentals, we can graph the equation using a graphing calculator or software.

import numpy as np
import matplotlib.pyplot as plt
def vhs_rentals(x):
return 9.92 * (0.8209)**x

x = np.arange(2000, 2020)

y = vhs_rentals(x)

plt.plot(x, y)
plt.xlabel('Year')
plt.ylabel('Number of VHS Movie Rentals')
plt.title('Decline in VHS Movie Rentals')
plt.show()

Conclusion

The exponential regression equation provides a mathematical model for the decline in VHS movie rentals. The equation shows that the number of VHS movie rentals decreases at an exponential rate, with a starting point of 9.92 in the year 2000 and a rate of decline of 0.8209.

Limitations

While the equation provides a good fit to the data, there are some limitations to consider. The equation assumes a constant rate of decline, which may not be the case in reality. Additionally, the equation does not take into account other factors that may influence the decline in VHS movie rentals, such as changes in consumer behavior or technological advancements.

Future Research

Future research could focus on developing a more comprehensive model that takes into account multiple factors influencing the decline in VHS movie rentals. Additionally, researchers could explore the implications of this decline for the film industry and the broader economy.
