In this video lesson we will learn how to determine if a relation is a function using a mapping diagram and the vertical line test. We will discover that you can represent a relation using a mapping diagram, a table of values, ordered pairs or a graph. We will review the meaning of independent and dependent variables and how the relate to a function. You will learn that an equation is a function rule where y is a function of x. We will use the function rule to create a table of values to graph and determine the set of values that make the domain and the range. Student practice is embedded in the lesson and modeled exemplar solutions are provided.

Common Core Math Standard
Understand the concept of a function and use function notation.
HSF.IF.A.1 Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
