Answer:
-0.5
Step-by-step explanation:
Average rate of a function f(x) in the interval a to b is given by
Average rate of change = ![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
Here we are given a graph. From the graph we find out f value at end points
a=0: f(0) = 2: b=2:f(2) = 1
Substitute in the average rate of change formula to get
f(2)-f(0) =1-2 =-1
b-a = 2
Hence average rate of change = -1/2
=-0.5
(Negative value indicates the change is decrease. i.e. when x increases f decreases)
