If I got it right it is 9.59166305.
7 - N (replace N with 34)
7 - 34
- 27
The answer is - 27
Average rate of change of the function 
Solution:
Given function:
from x = 1 to x = 5
Substitute x = 1 and x = 5 in f(x).


Let us find the average rate of change of the function.
Average rate of change

Here a = 1 and b = 5.

Substitute f(5) and f(1).



Average rate of change of the function 
Answer: f(x)=−3x+4
Step-by-step explanation:
In a function
y
=
f
(
x
)
,
x
is the independent variable and
y
is the dependent variable.
So to represent the given equation as a function, it is just enough to solve it for y
