This document discusses translating functions by shifting the graph of a function up or down. It provides examples of sketching the functions f(x) = x^2, f(x) = sin(x), f(x) = sin(x) + 1, and f(x) = sin(x) - 1. It defines translation of a function as a transformation where every point is moved in the same direction. The document assigns exercises questions 4 through 13, 15, and 17.
