Relations and Functions | |
Definition--Functions and Relations Concepts--Function Machine | Function MachineTopicFunctions and Relations DefinitionA function machine is a conceptual tool used to understand how functions work by visualizing inputs and outputs. DescriptionThe function machine is a useful educational tool that helps students grasp the concept of functions by visualizing the process of converting inputs into outputs. It emphasizes the idea that a function takes an input, processes it according to a specific rule, and produces an output. For example, if the function is f(x) = x + 2 |

Definition--Functions and Relations Concepts--Function Notation | Function NotationTopicFunctions and Relations DefinitionFunction notation is a way to represent functions in the form f(x), where f denotes the function and x denotes the input variable. DescriptionFunction notation is a standardized way to write functions, making it easier to understand and communicate mathematical relationships. It is widely used in algebra, calculus, and other branches of mathematics. For example, the notation f(x) = x2 |

Definition--Functions and Relations Concepts--Function Table | Function TableTopicFunctions and Relations DefinitionA function table is a table that lists input values and their corresponding output values for a given function. DescriptionFunction tables are useful tools in mathematics for organizing and analyzing the relationship between inputs and outputs of a function. They help in visualizing how a function behaves and in identifying patterns. For example, a function table for f(x) = 2x + 1 |

Definition--Functions and Relations Concepts--Piecewise Functions | Piecewise FunctionsTopicFunctions and Relations DefinitionPiecewise functions are functions defined by multiple sub-functions, each applying to a certain interval of the domain. |
Special Functions | |
Definition--Functions and Relations Concepts--Range of a Function | Range of a FunctionTopicFunctions and Relations DefinitionThe range of a function is the set of all possible output values (y-values) that the function can produce. DescriptionUnderstanding the range of a function is crucial in mathematics because it defines the scope of possible outputs. The range is determined by the function's rule and the domain. For example, the range of the function f(x) = x2 |
Relations and Functions | |
Definition--Functions and Relations Concepts--Recursive Function | Recursive FunctionTopicFunctions and Relations DefinitionA recursive function is a function that calls itself in its definition. DescriptionRecursive functions are important in mathematics and computer science because they provide a way to solve problems by breaking them down into simpler sub-problems. They are defined by a base case and a recursive case. For example, the factorial function f(n) = n⋅f(n−1) with f(0)=1 |
Relations and Functions | |
Definition--Functions and Relations Concepts--Reflecting a Function | Reflecting a FunctionTopicFunctions and Relations DefinitionReflecting a function involves flipping the graph of the function over a specified axis. DescriptionReflecting functions is significant in mathematics because it helps in understanding the symmetry and transformations of functions. A function can be reflected over the x-axis or y-axis, changing its orientation. For example, reflecting the function f(x) = x2 |
Relations and Functions | |
Definition--Functions and Relations Concepts--Relation | RelationTopicFunctions and Relations DefinitionA relation is a set of ordered pairs, where each element from one set is paired with an element from another set. |
Relations and Functions | |
Definition--Functions and Relations Concepts--Step Function | Step FunctionTopicFunctions and Relations DefinitionA step function is a function that increases or decreases abruptly at certain points, creating a series of steps. |
Special Functions | |
Definition--Functions and Relations Concepts--Translating a Function | Translating a FunctionTopicFunctions and Relations DefinitionTranslating a function involves shifting the graph of the function horizontally, vertically, or both, without changing its shape. DescriptionTranslating functions is significant in mathematics because it helps in understanding how functions behave under shifts. A function can be translated horizontally by adding or subtracting a constant to the input, and vertically by adding or subtracting a constant to the output. For example, translating the function f(x) = x2 horizontally by 2 units results in |
Relations and Functions | |
Definition--Functions and Relations Concepts--Vertical Line Test | Vertical Line TestTopicFunctions and Relations DefinitionThe vertical line test is a method used to determine if a graph represents a function by checking if any vertical line intersects the graph more than once. DescriptionThe vertical line test is important in mathematics because it helps in identifying whether a given graph represents a function. If a vertical line intersects the graph at more than one point, then the graph does not represent a function. This test is used in various fields, including computer science for validating functions in programming and in mathematics for analyzing graphs. For example, the graph of |

Definition--Functions and Relations Concepts--Visual Models of Functions | Visual Models of FunctionsTopicFunctions and Relations DefinitionVisual models of functions are graphical representations that illustrate the relationship between input and output values of functions. DescriptionVisual models of functions are important in mathematics because they provide a clear and intuitive way to understand how functions behave. These models include graphs, tables, and diagrams that show the relationship between input and output values. For example, the graph of f(x) = x2 |
