Document Summary
O a function f is a rule that assigns to each element x in a set d exactly one element, called. A symbol that represents a number in the range of f is called a: another way to picture a function is by an arrow diagram, the most common method for visualizing a function is its graph. If f is a function with domain d, then its graph is the set of ordered pairs: there are four possible ways to represent a function: If a function f satisfies f(-x)=f(x) for every number x in its domain, then f is called an even function. The geometric significance of an even function is that its graph is symmetric with respect to the y-axis. If f satisfies f(-x)=-f(x) for every number x in its domain, then is called an odd function. The graph of an odd function is symmetric about the origin.
