Key Concepts

Graph Sketching

Graph sketching involves combining information about a function—including its critical points, asymptotic behavior, and intercepts—to produce an accurate visual representation of its behavior. This process helps in understanding how the function behaves locally and globally and is an important step in visualizing the impact of relative extrema on the graph.

Relative Extrema

Relative extrema are points in a function where it reaches a local maximum or minimum, meaning that within a small interval around the point, no other function values are higher (for a maximum) or lower (for a minimum). These extrema are found by analyzing changes in the function’s behavior rather than relying solely on global comparisons.

Critical Points

Critical points are values in the domain of a function where its derivative is zero or undefined. These points are important because they are where the function’s rate of change potentially shifts direction, making them candidates for local maxima or minima.

First Derivative Test

The first derivative test is a method for determining the nature of critical points by examining the sign of the derivative before and after these points. A change from positive to negative indicates that the function has a local maximum, while a change from negative to positive suggests a local minimum.

Rational Function Analysis

Rational functions, which are expressed as the ratio of two polynomials, often require careful analysis due to features like vertical or horizontal asymptotes and potential restrictions in the domain. Understanding these characteristics is essential for determining the overall behavior of the function and for identifying points of interest such as relative extrema.
