The absolute minimum value of a function is the lowest point on the graph of the function over its entire domain.
A local minimum is a low point on a graph within a specific interval but not necessarily the overall lowest point.
A critical point occurs when the derivative of a function is either zero or undefined. It can be associated with maximums, minimums, or inflection points.
The domain of a function consists of all possible input values (x-values) for which the function is defined and meaningful.
