Question

find the average rate of change from a function rule find the average rate of change of the function f(x)=√x - x on the interval 4, 9. recall that the coordinates for the start of the interval are (4, -2). what are the coordinates for the end of the interval? (9, -6) (9, 6) (9, -12) (9, 12)

Explanation:

Step1: Find the value of the function at the end of the interval

The end of the interval is \(x = 9\). Given \(f(x)=\sqrt{x}+x\), substitute \(x = 9\) into the function.

So the coordinates are \((9,12)\)

Answer:

\((9,12)\)
