What is the average rate of change between x 4 and x8?

Answer 1

The average rate of change between two points on a function, (x_1) and (x_2), can be calculated using the formula (\frac{f(x_2) - f(x_1)}{x_2 - x_1}). In this case, if we denote the function values at (x_4) and (x_8) as (f(x_4)) and (f(x_8)), the average rate of change between (x = 4) and (x = 8) would be (\frac{f(8) - f(4)}{8 - 4} = \frac{f(8) - f(4)}{4}). You would need the specific function values to compute a numerical answer.
