I'd seriously appreciate it if anyone could ! : ) i'll give brainliest! show your work. the depth of a river changes after a heavy rainstorm. its depth, in feet, is modeled as a function of time, in hours. consider this graph of the function. write the average rate of change for the depth of the river, measured as feet per hour, between hour 9 and hour 18. round your answer to the nearest tenth.

y2 - y1 / x2 -x1

21 ft - 18 ft / 18hr - 9 hr

3 ft/9hr

1/3 ft/hr

SOLUTION

Your input: find the average rate of change of f(x)=x2 on the interval [1,3].

The average rate of change of f(x) on the interval [a,b] is f(b)−f(a)b−a.

We have that a=1, b=3, f(x)=x2.

Thus, f(b)−f(a)b−a=((3))2−(((1))2)3−(1)=4.

the average rate of change is 4.

rounded answer.

4.0

gimmee one of those gold crowns!
