1. Which of the following conditions guarantees a local extremum at a critical point c?

a

f'(c) = 0

b

f''(c) = 0

c

f'(c) = 0 and f''(c) ≠ 0

d

f'(c) is undefined

2. A point where the derivative of a function is zero or undefined is called a   point.

3. The   Theorem states that if a function is continuous on a closed interval [a, b], then it must attain both a maximum and minimum value on that interval.

4. Find the critical points of the function f(x) = x³ - 6x² + 5.

5. A local maximum is always the absolute maximum of a function.

T

True

F

False

6. Consider the graph of a function f(x) below. Identify the approximate x-values where local maxima and minima occur.
