Key Concepts

Monotonicity and Derivative Tests

Monotonicity describes the behavior of functions in terms of being increasing or decreasing over intervals. This concept is typically examined by using the first derivative test, where a positive derivative indicates an increasing function and a negative derivative indicates a decreasing function. Such analysis is key in understanding the overall behavior of functions, including those defined by integrals.

Rational Functions

Rational functions are expressions defined as the quotient of two polynomials. Analyzing these functions often involves understanding their domains, asymptotic behavior, and discontinuities, which are essential when determining properties such as range and limits.

Determining the Range of a Function

Determining the range involves finding all the possible output values of a function. This process includes analyzing the function’s expression, understanding its behavior near critical points and asymptotes, and solving relevant equations to see which values are attainable.
