Graphs of Functions Page 1 of 5 Â§ 2.2: Graphs of Functions Graphing Functions Example 1 Graphing Functions Sketch the graph of the following functions. (a) ? ( Â¡ ) = Â¡ 2 (b) ? ( Â¡ ) = Â¡ 3 (c) ? Â¡Â¢ = Â£ Â¡ (d) ? Â¡Â¢ =  Â¡  { Â¤Â¡ , ? Â¡Â¢Â¥ : Â¡ âˆˆ } The Graph of a Function If f is a function with domain A , then the graph of f is the set of ordered pairs In other words, the graph of f is the set of all points ( x , y ) such that y = f(x) ; that is, the graph of f is the graph of the equation y = f(x). Math 1650 Lecture Notes Â§2.2 Jason Snyder, PhD. Graphs of Functions Page 2 of 5 Getting Information from the Graph of a Function The graph of a function helps us picture the domain and range of the function on the xaxis and yaxis as shown below. Example 2 Finding the Domain and Range from a Graph Below is the graph of the function ? Â¡Â¢ = Â£ 4 âˆ’ Â¡ 2 . Find the domain and range of ? ....
