This document discusses graphs of cubic and reciprocal functions. It provides examples of cubic functions in the form f(x)=ax^3+bx^2+cx+d and describes their key properties: the domain is all real numbers, the range is all real numbers, the y-intercept is d, and the x-intercepts are found by solving the cubic equation. Graphs of the functions y=x^3+4 and y=-x^3-4 are shown as an example. The document also discusses reciprocal functions in the form y=a/x and provides a table of values for the function y=6/x as an example graph. Students are given practice questions to test their understanding of cubic functions
