This document describes how to graph linear and quadratic functions. It explains that a linear function has the form y=ax+b, where a and b are constants. It provides two methods to graph linear functions: tabulation and the abbreviated method. For quadratic functions of the form y=ax^2+bx+c, it explains how to find the vertex and x-intercepts using formulas. The vertex is found as (-b/2a, -b^2/4a) and the x-intercepts are found by solving the quadratic formula. Examples are given to demonstrate graphing quadratic functions step-by-step.
