Exponential Functions and Linear Equations

The video is a crash course review of Algebra 1, covering linear equations, quadratic equations, and exponential functions. It explains key concepts such as systems of equations, solutions, graphing techniques using Desmos, properties of parabolas, and the role of exponents in exponential functions. The video also introduces 'P man' as a mnemonic for handling exponents and discusses the concept of asymptotes in exponential graphs.
