Solution
Let's break down the two parts of the question based on the table provided in your image.
Part a. What is the value of ?
From the table, you can directly read off the value of .
- When , .
Part b. Calculate the average rate of change from to . Use your answer to find .
The average rate of change between two points is calculated using the formula:
For and :
Substitute the values from the table:
Now calculate:
So, the average rate of change is .
Use this to estimate .
Since 7 is between 5 and 10, we can assume a linear change between those points. To find , we'll use the slope and apply the point-slope form of the line between and . Let's take the point :
Substitute , , and :
So, .
Summary:
- Average rate of change between and is
Would you like any additional details on the process?
Here are 5 related questions to further your understanding:
- How would the calculation change if the points between 5 and 10 were not linear?
- How can you use the concept of the average rate of change in real-world problems?
- Can you calculate the rate of change between and ?
- How does the slope of a function inform us about its behavior over an interval?
- What would be assuming the same average rate of change applies beyond ?
Tip: When dealing with linear approximations, the assumption is that the rate of change remains constant within the interval, but this might not always be true for non-linear functions!
