To find f(4), you just replace wherever x is with 4.
f(x) = 3x - 1
⇒ f(4) = 3*(4) - 1
⇒ f(4)= 12-1
⇒ f(4)= 11.
f(4) = 11 is the final answer.

Answer:
1/3
Step-by-step explanation:
3*3*3=27
1/3*1/3*1/3=1/27
The formula for the average rate of change is given as:

From the interval provided, take

Comparing on the graph,

Inputting the values into the equation for average rate of change,

Therefore, the average rate of change for the interval -9 ≤ x ≤ -8 is 60.
