What is the average rate of change over the interval [1,2]Type the numerical value for your answer as a whole number, decimal, or fractionMake sure answers are completely simplified

Answer 1

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:

`r=(y_2-y_1)/(x_2-x_1)=(25-50)/(2-1)=-(25)/(1)=-25`

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