<u>Answer:</u>
3 and 60
<u>Step-by-step explanation:</u>
For the given proportions, , 3 and 60 are the extremes while 12 and 15 are the means.
To understand this, we can take a look at an example.
Suppose two ratios a:b and c:d are in proportion.Then it can be expressed as :
Here, a and d are the extreme ends and b and c are the means.
If the function is and f(4) − f(1) = f '(c)(4 − 1) then there is not any answer.
Given function is and f(4) − f(1) = f '(c)(4 − 1).
In this question we have to apply the mean value theorem, which says that given a secant line between points A and B, there is at least a point C that belongs to the curve and the derivative of that curve exists.
We begin by calculating f(2) and f(5):
f(2)=
f(2)=1
f(5)=
f(5)=1
And the slope of the function:
(x)=
(c)=0
Now,
=-2
=0
-2 is not equal to 0. So there is not any answer.
Hence if the function is and f(4) − f(1) = f '(c)(4 − 1) then there is not any answer.
