Key Concepts

Function Transformations

This concept involves altering the basic form of a function by applying shifts, reflections, and stretches. In the context of graphing a function like a cubic, understanding transformations—such as horizontal shifts, vertical shifts, and reflections—is crucial to sketch the graph accurately and determine the resulting behavior of the function.

Derivatives

Derivatives provide the instantaneous rate of change of a function and are a fundamental tool in calculus. By calculating the derivative of a function, we can analyze where the function is increasing or decreasing, which is essential for understanding the shape and behavior of its graph.

Critical Points and the First Derivative Test

Critical points, where the derivative equals zero or does not exist, are key in identifying changes in a function’s monotonic behavior. The First Derivative Test uses these points to determine whether a function is increasing or decreasing on intervals around them, thereby providing a systematic approach to analyzing the function’s behavior.

Monotonicity

Monotonicity refers to the property of a function being either entirely non-decreasing or non-increasing over an interval. Determining the intervals where a function is increasing or decreasing involves studying the sign of its derivative across its domain.
