(AP Calc) the graph of the function f shown above has three line segments....

I am Lyosha [343]

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 1, 6 ] and from the graph

f(b) = f(6) = 0

f(a) = f(- 1) = 0, thus

average rate of change = $\frac{0-0}{6+1}$ = $\frac{0}{7}$ = 0
