Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 4, 3 ] , then
f(b) = f(3) = 3² - 3 - 8 = 9 - 3 - 8 = - 2
f(a) = f(- 4) = (- 4)² - (- 4) - 8 = 16 + 4 - 8 = 12 , tus
average rate of change = 
= 
= - 2

Answer: angle N
Step-by-step explanation:
The order of the triangle names HAS to indicate which angles are congruent. First letters are congruent (D and M), second letters are congruent (E and N), and third are congruent (F and O). Also, the diagram shows that the triangles are reflections of each other. reflect one triangle onto the other, and you see that E and N overlap.
