The Value, { V(m) $}$, Of A Comic Book { M $}$ Months After Publication Has An Average Rate Of Change Of -0.04 Between { M=36 $}$ And { M=60 $}$. Which Statement Must Be True?A. The Value Of The Comic Book
The Value of a Comic Book: Understanding Average Rate of Change
In the world of comic books, the value of a particular issue can fluctuate over time. This fluctuation can be influenced by various factors, including the popularity of the series, the condition of the comic book, and the demand for it among collectors. In this article, we will explore the concept of average rate of change and how it can be applied to the value of a comic book.
The average rate of change of a function is a measure of how much the function changes over a given interval. It is calculated by finding the difference in the function's values at the endpoints of the interval and dividing by the length of the interval. In mathematical terms, the average rate of change of a function f(x) over the interval [a, b] is given by:
Let's consider a comic book with a value V(m) that changes over time. We are given that the average rate of change of the value of the comic book is -0.04 between m = 36 and m = 60. This means that for every month that passes between 36 and 60 months after publication, the value of the comic book decreases by an average of 0.04.
We are asked to determine which statement must be true based on the given information. Let's analyze the possible statements:
- A. The value of the comic book decreases by 1.44 between m = 36 and m = 60.
- B. The value of the comic book increases by 0.08 between m = 36 and m = 60.
- C. The value of the comic book remains the same between m = 36 and m = 60.
To determine which statement is true, we need to calculate the change in value of the comic book between m = 36 and m = 60. We can use the formula for average rate of change:
Simplifying the equation, we get:
Now that we have calculated the change in value, let's evaluate the possible statements:
- A. The value of the comic book decreases by 1.44 between m = 36 and m = 60. This statement is false, as we calculated that the value decreases by 0.96.
- B. The value of the comic book increases by 0.08 between m = 36 and m = 60. This statement is also false, as we calculated that the value decreases by 0.96.
- C. The value of the comic book remains the same between m = 36 and m = 60. This statement is false, as we calculated that the value decreases by 0.96.
Based on the given information, we can conclude that the value of the comic book decreases by 0.96 between m = 36 and m = 60. This means that statement A is the closest to being true, but it is still incorrect. The correct statement is not among the options provided.
The final answer is not among the options provided. However, we can conclude that the value of the comic book decreases by 0.96 between m = 36 and m = 60.
It's worth noting that the average rate of change is a measure of the average rate at which the value of the comic book changes over a given interval. It does not necessarily mean that the value changes at a constant rate over the entire interval. The value of the comic book may change at a different rate at different points in the interval.

The Value of a Comic Book: Q&A
In our previous article, we explored the concept of average rate of change and how it can be applied to the value of a comic book. We calculated that the value of the comic book decreases by 0.96 between m = 36 and m = 60. In this article, we will answer some frequently asked questions about the value of a comic book and its average rate of change.
Q: What is the average rate of change of the value of a comic book? A: The average rate of change of the value of a comic book is -0.04 between m = 36 and m = 60.
Q: How does the average rate of change relate to the value of the comic book? A: The average rate of change is a measure of how much the value of the comic book changes over a given interval. In this case, the value decreases by an average of 0.04 per month between m = 36 and m = 60.
Q: Can the value of a comic book change at a constant rate over the entire interval? A: No, the value of a comic book may change at a different rate at different points in the interval. The average rate of change is a measure of the average rate at which the value changes over the entire interval.
Q: How can I calculate the average rate of change of the value of a comic book? A: To calculate the average rate of change, you need to find the difference in the value of the comic book at the endpoints of the interval and divide by the length of the interval. The formula for average rate of change is:
Q: What is the significance of the average rate of change in the context of comic book values? A: The average rate of change is important because it helps collectors and investors understand how the value of a comic book changes over time. This information can be used to make informed decisions about buying, selling, and holding comic books.
Q: Can the average rate of change be used to predict the future value of a comic book? A: While the average rate of change can provide insights into the past behavior of a comic book's value, it is not a reliable predictor of future value. Many factors can influence the value of a comic book, including market trends, supply and demand, and changes in the condition of the comic book.
Q: How can I use the average rate of change to make informed decisions about buying and selling comic books? A: To use the average rate of change to make informed decisions, you need to consider the following factors:
- The average rate of change of the value of the comic book over the desired interval
- The current value of the comic book
- The expected future value of the comic book based on market trends and other factors
- The costs associated with buying and selling the comic book
The average rate of change is an important concept in understanding the value of a comic book. By calculating the average rate of change, collectors and investors can gain insights into the past behavior of a comic book's value and make informed decisions about buying, selling, and holding comic books.
