Verify that Rolle's Theorem can be applied:
f(2) = 2^3 - 10*2^2 + 31*2 - 30 = 0 f(5) = 5^3 -
10 * 5^2 + 31*5 - 30 = 0
Rolle's Theorem can be applied.
First I found the derivative of f(x) = x^3 - 10x^2 + 31x - 30:
d/dx(x^3 - 10x^2 + 31x - 30)
= d/dx(x^3) - d/dx(10x^2) + d/dx(31) - d/dx(30)
= 3x^2 - 20x + 31
Then, I solved for zero:
3x^2 - 20x + 31 = 0
Using the quadratic formula(-(-20) +- sqrt((-20)^2 - 4*3*31)) / (2*3)
=(-(-20) +- 2sqrt(7)) / (2*3)
= (10 +- sqrt(7)) / 3

Feedback:
,The following is Mobius' explanation for a solution to this question. You can use this and other
online references as a guide, but your explanation should be in your own words.
The function is continuous on the interval and
differentiable on the interval
. Since , there exists at least one in such that .
The derivative of is
.
Solve .
Therefore, the values of such that are and .
Question2: Score 4/4
Verify that the Mean Value Theorem can be applied to the function on the interval . Then find
the value of in the interval that satisfies the conclusion of the Mean Value Theorem.
Enter the exact answer.
