Essential Questions:

How can you represent and describe functions? Can functions represent real-world situations?

Understandings:

A function is a relationship between variables in which each value of the input variable is associated with a unique value of the output variable. Functions can be represented in a variety of ways, such as graphs, tables, equations, or words. Each representation is particularly useful in certain situations.
Many real-world mathematical problems can be represented algebraically. These representations can lead to algebraic solutions. A function that models a real world situation can then be used to make estimates or predictions about future occurrences.
