Answer 1

To calculate the average rate of change of a function over an interval \([a, b]\), you can use the formula:

\[
\text{Average rate of change} = \frac{f(b) - f(a)}{b - a}
\]

From your question, it appears we have the values at the points:

- \(f(3) = 4\) (you mentioned that for \(x=3\), the value is at the bottom)
- \(f(4) = 20\) (you mentioned that for \(x=4\), the value is at the top)

Now, applying these values to the formula:

\[
\text{Average rate of change} = \frac{f(4) - f(3)}{4 - 3} = \frac{20 - 4}{4 - 3} = \frac{16}{1} = 16
\]

Thus, the average rate of change over the interval \([3, 4]\) is **16**.
