Key Concepts

Derivative

A derivative represents the instantaneous rate of change of a function. It is used to determine the behavior of the function, including identifying intervals where the function is increasing or decreasing. Finding the derivative is a crucial step in locating potential extrema (maxima and minima) by finding where the derivative equals zero or does not exist.

Critical Points

Critical points are the points in the domain of a function where the derivative is zero or undefined. These points are candidates for local maxima, local minima, or saddle points. By identifying critical points, one can determine where a function might change its increasing or decreasing behavior.

Relative Extrema

Relative extrema refer to the local maximum and minimum values of a function. These are the points at which the function's value is higher or lower, respectively, than at nearby points. Determining relative extrema helps in understanding the local behavior of the function and is a key concept in optimization and graph analysis.

First Derivative Test

The first derivative test is a method for classifying critical points by analyzing the sign of the derivative on either side of these points. A change in the derivative from positive to negative typically indicates a local maximum, while a change from negative to positive indicates a local minimum.

Graph Sketching

Graph sketching involves creating a visual representation of a function based on its algebraic properties and calculated key features such as critical points, relative extrema, and inferred behavior at infinity. For polynomial functions, understanding the number and type of extrema and the end behavior facilitates an accurate sketch of the graph.
