This unit focuses the cluster of Understanding the concept of a function and use function notation in the Interpreting Function domain of the Common Core State Standards for Mathematics. In this unit students will be introduced to functions and their properties. By the end of the unit students will be able to identify the domain and range of a given functions, in addition they will understand the one-to-one relationship between numbers in the domain and numbers in the range. When speaking of functions students will be able to use the correct vocabulary, likewise, they will use correct notation when referencing them on paper. Students will also be able to evaluate a given function with given an input value for the function. This unit will also introduce student to common functions, knows as parents functions, that they will often see throughout the rest of their mathematical careers. The last things students will learn in this unit is how to recognize that sequences are functions and how to express some sequences in function notation.
