Unformatted text preview: y ) is the value of the function f at x . The range of the function f is the set of all possible values of f( x ) as x varies throughout the domain. The range can also be thought of as the set of output values. Example: Find the domain and range of the functions a) b) Four possible ways to represent a function are as follows: 1. Verbally (by a description in words) 2. Numerically (by a table of values) 3. Visually (by graph) 4. Algebraically (by an explicit formula) Note that the graph of a function is a curve in the x-y plane. A curve in the x-y plane is the graph of a function of x if and only if no vertical line intersects the curve more than once. Work # 2, & 4 on page 8, # 20, 28, 37 on page 9 A Catalog of Essential Functions Objectives: Students should be able to You should be familiar with the graphs of the following commonly occurring functions. 1. Linear functions: f( x ) = m x + b. What does m represent? Explain what it means. 2....
