What is the average rate of change from 0 to 2 of the function represented by the graph

-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 =

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)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
