If f'(x) = 0 for all values of x, then f(x) is

If the derivative of a function f(x) is equal to 0 for all values of x, then the function f(x) is said to have a critical point at each of those values

If the derivative of a function f(x) is equal to 0 for all values of x, then the function f(x) is said to have a critical point at each of those values.

A critical point is a point on the graph of a function where the derivative is either zero or does not exist. In this case, since f'(x) = 0 for all x, it means that f(x) has critical points at every x-value in its domain.

At a critical point, the slope of the tangent line to the graph of the function is 0. This means that the function either has a local maximum, a local minimum, or a horizontal point of inflection at each critical point.

To determine whether a given critical point corresponds to a local maximum, local minimum, or a point of inflection, further analysis is needed. This can involve examining the second derivative or applying other techniques such as using the First or Second Derivative Test.

In summary, if f'(x) = 0 for all values of x in the domain of f(x), then f(x) has a critical point at each of those x-values. Further investigation is required to determine the nature of each critical point.
