Key Concepts

Relative Extrema

Relative extrema are points on the graph of a function where the function reaches a local maximum or a local minimum. These points are important because they represent peaks and valleys in the function’s behavior and are determined by examining where the function changes from increasing to decreasing or vice versa.

Critical Points

Critical points are the values of x in the domain of a function where its derivative is zero or undefined. These points are potential candidates for relative extrema since the function's rate of change may switch direction from increasing to decreasing or vice versa.

Differentiation

Differentiation is the process used to compute the derivative of a function, which measures the function's rate of change at any given point. For polynomial functions, differentiation involves applying power rule and constant multiple rule, resulting in a derivative that can be set equal to zero to find critical points.

Second Derivative Test

The second derivative test is a method used to classify critical points by calculating the second derivative at those points. If the second derivative is positive, the function is concave up and the critical point is a local minimum; if it is negative, the function is concave down and the critical point is a local maximum.

Graph Sketching

Graph sketching involves plotting a function by considering its key characteristics such as intercepts, critical points, inflection points, and asymptotic behavior. Understanding how relative extrema and the concavity of the function interact helps in accurately drawing a graph that reflects the function's behavior over its domain.
