(AP Calc) the graph of the function f shown above has three line segments....
I am Lyosha [343]

Answer:

B

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

So first thing you need to understand is that ABC and AFE are congruent triangles. This means we can find the other angles, based on ABC:

Angle FAE = 26.56505118 degrees
Angle AEF = 63.43494882 degrees

Angles ECD and DEC are both 45 degrees

Now, we can find the angles in ACE:

AEC = 71.56505118 degrees
ECA = 71.56505118 degrees
CAE = 36.86989764 degrees
