Math Problem Statement

Given a table for f(x) and g(x), find the average rate of change of g(x) from x = 4 to x = 6 and f(x) from x = 6 to x = 7.

Solution

The image shows a table for the functions f(x)f(x) and g(x)g(x), along with a request to find the average rates of change for both functions over specific intervals:

  1. Average rate of change of g(x)g(x) from x=4x = 4 to x=6x = 6: The average rate of change formula is given by: Average rate of change=g(x2)g(x1)x2x1\text{Average rate of change} = \frac{g(x_2) - g(x_1)}{x_2 - x_1} For this case: g(6)g(4)64\frac{g(6) - g(4)}{6 - 4}

  2. Average rate of change of f(x)f(x) from x=6x = 6 to x=7x = 7: Similarly, the formula applies: f(7)f(6)76\frac{f(7) - f(6)}{7 - 6}

Let's extract the corresponding values from the table and compute these.

From the table:

  • g(6)=5g(6) = 5, g(4)=4g(4) = 4
  • f(7)=4f(7) = 4, f(6)=8f(6) = 8

Now let's compute these average rates of change.The average rates of change are as follows:

  1. The average rate of change of g(x)g(x) from x=4x = 4 to x=6x = 6 is 0.50.5.
  2. The average rate of change of f(x)f(x) from x=6x = 6 to x=7x = 7 is 4.0-4.0.

Would you like more details on how these values were calculated, or do you have any further questions?

Here are 5 related questions to expand on the topic:

  1. What is the geometric interpretation of the average rate of change?
  2. How does the average rate of change relate to the concept of a derivative?
  3. Can the average rate of change be used to estimate instantaneous rates of change?
  4. What does a positive or negative average rate of change indicate about the behavior of the function?
  5. How does the average rate of change differ across linear and nonlinear functions?

Tip: The average rate of change formula is similar to the slope formula for a straight line, but it applies to any two points on a function.
