| The concept of a function is considered one of the most important concepts in mathematics. A function is a unique relation that transforms an input to an output. The input can be a numerical value, an algebraic expression, a quantity, or some other mathematical object. A functional transformation is a unique, one-to-one correspondence, meaning that each function input maps to one, and only one output. In math we visualize functions as graphs, tables, charts, or symbols. In this module you will develop your understanding of functions and how to manipulate their representations. |
