Answer

Divide the difference by the length of the interval: $\frac{f (10) - f (1)}{10 - 1}$ .

Steps

Step 1 ：Find the values of the function at the endpoints of the interval: f(1) and f(10).

Step 2 ：Calculate the difference of the function values: f(10) - f(1).

Step 3 ：Divide the difference by the length of the interval: $\frac{f (10) - f (1)}{10 - 1}$ .
