http://www.freemathvideos.com In this video series we will investigate the basics of what you will need to know to be successful in Pre-Calculus. We will start with learning about linear equations and writing the equation of a line as well as determining the slope. We will then discuss quadratic functions to be able to find the roots and convert from standard form to vertex form. We will investigate graphing and evaluating piecewise functions and learn how to determine the domain and range of a graph. Especially the domain of a rational expression. Lastly we will discuss end-behavior of different functions
f(x) = 2x - 3; g(x) = x + 1; Evaluate (f o g)(3)
