1

For the function f(x) = x³ + ax² + bx defined on [1, 2], Rolle's theorem holds at c = 4/3. What are the values of a and b?

2

For f(x) = x³ - 6x² + ax + b on [1, 3], Rolle's theorem holds with c = 2 + 1/√3. What is the value of a?

3

Rolle's theorem is applied to f(x) = (x - a)^n (x - b)^m on [a, b] where m, n ∈ ℕ. The value of c guaranteed by Rolle's theorem is:

4

For f(x) = log[(x² + ab)/(x(a+b))] on [a, b] where 0 < a < b, the value of c guaranteed by Rolle's theorem is:

Sample Questions

1mcq

Rolle's Theorem guarantees the existence of c ∈ (a,b) such that:

Show answer

f'(c) = 0

The conclusion of Rolle's Theorem is that f'(c) = 0 for some c in the open interval (a,b).

2mcq

How many conditions does Rolle's Theorem require?

Show answer

3

Three conditions: (i) f continuous on [a,b], (ii) f differentiable on (a,b), (iii) f(a) = f(b).

3mcq

Lagrange's MVT does NOT require which of the following?

Show answer

f(a) = f(b)

LMVT only requires continuity on [a,b] and differentiability on (a,b). The condition f(a)=f(b) is needed only for Rolle's Theorem.

4mcq

The conclusion of LMVT is:

Show answer

f'(c) = [f(b)-f(a)]/(b-a)

LMVT states f'(c) = [f(b)-f(a)]/(b-a) for some c ∈ (a,b). This equals the slope of chord AB.
