Answer:
Yes, she is correct
Step-by-step explanation:
All you really have to do is multiply 1/5 and 3/4. We can separate her backyard in 5 equal parts. In one of those parts, we have her garden, and we break it down into 4 pieces, and make three of those tomato gardens. Now if we break all 5 parts of her backyard into 4 pieces, we can double check our answer, and see that there are 20 pieces, but only 3 have tomatoes. Of course, that's only to double check, but you could also use this method as a model.
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.
