Respuesta :

To calculate the average rate of change over the interval [1,2] we need to identify the points in the extremes of the interval.

This points are (1,50) and (2,25).

We calculate the average rate of change as the slope:

[tex]r=\frac{y_2-y_1}{x_2-x_1}=\frac{25-50}{2-1}=-\frac{25}{1}=-25[/tex]

Answer: the rate of change over [1,2] is -25.
