N= 9
these are the answers
Common difference r will be the difference between next two values of number row, so we take e.g. second minus first: r=9.4-6=3.4. You can see, that this value is constant as we go through next pairs of values.
Answer:
3x^2-x+5.2f\left(-3\right)-f\left(4\right) =
3x^2-x-19.6f
Step-by-step explanation:
3x^2-x+5.2f\left(-3\right)-f\left(4\right)
=3x^2-x-5.2f\cdot \:3-f\cdot \:4
=3x^2-x-15.6f-4f
=3x^2-x-19.6f
Given:
Consider the function is:
To find:
The average rate of change over the interval 2 ≤ x ≤ 4.
Solution:
We have,
At ,
At ,
The average rate of change of a function f(x) over the interval [a,b] is:
So, the average rate of change over the interval 2 ≤ x ≤ 4 is:
On further simplification, we get
Therefore, the average rate of change over the interval 2 ≤ x ≤ 4 is 2.
