College algebra is a fundamental course that covers a wide range of algebraic principles and concepts. It is a prerequisite course for many fields of study, including mathematics, science, engineering, and business. According to the College Board, “College algebra covers topics such as equations and inequalities, graphs and functions, polynomial and rational functions, exponential and logarithmic functions, and systems of equations.”

Equations and Inequalities: College algebra starts with a review of basic algebra concepts such as solving linear equations, quadratic equations, and systems of equations with two variables. Students learn how to graph linear equations and solve linear inequalities. They also learn how to solve absolute value equations and inequalities and quadratic inequalities.

Graphs and Functions: One of the essential topics in college algebra is learning how to graph functions. Students study various types of functions such as linear, quadratic, polynomial, rational, exponential, and logarithmic functions. They also learn how to find the domain and range of the functions, the intercepts, and the asymptotes. As graphing is a significant component of college algebra, it is crucial to understand it thoroughly. As David Mamet, the American playwright and director, said, “Understanding the laws of nature does not mean that we are immune to their operations.”

Polynomial and Rational Functions: Polynomial and rational functions are a significant focus of college algebra. Students learn to factor polynomials and solve polynomial equations. They also learn how to graph polynomial functions of various degrees. Rational functions are covered, with a focus on solving equations involving rational functions.

Exponential and Logarithmic Functions: Students learn about exponential and logarithmic functions and their properties. They learn how to solve exponential and logarithmic equations, including applications such as compound interest and exponential growth and decay.

Systems of Equations: College algebra covers systems of equations with two variables and systems with three variables. Students learn how to solve these equations using the substitution method, the elimination method, and matrices.
