Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 1, 4 ] , then
f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36
f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then
average rate of change = 
= 
= 
= - 6

Answer:
x < -6
Step-by-step explanation:
-5x - 8 > 22
Add 8 to both sides: -5x > 30
Divide both sides by 5: -x > 6
Divide both sides by -1 (reverse sign): x < -6
