Q. If a function f(x) is defined as f(x) = x^3 - 3x + 2, what can be inferred about its behavior at critical points?
A.
It has no critical points.
B.
It has one local maximum and one local minimum.
C.
It is always increasing.
D.
It is always decreasing.
Solution
To find critical points, we take the derivative and set it to zero. The function has one local maximum and one local minimum based on the nature of cubic functions.
Correct Answer:
B
— It has one local maximum and one local minimum.
Q. If a function f(x) is defined as f(x) = x^3 - 3x, what is the nature of its critical points?
A.
They can be local maxima, local minima, or points of inflection.
B.
They are always local maxima.
C.
They are always local minima.
D.
They do not exist.
Solution
Critical points of a function can be local maxima, local minima, or points of inflection, depending on the behavior of the function around those points.
Correct Answer:
A
— They can be local maxima, local minima, or points of inflection.
