Definition--Functions and Relations Concepts--Absolute Value Function | Absolute Value Function
TopicFunctions and Relations DefinitionAn absolute value function is a function that contains an algebraic expression within absolute value symbols. It is defined as $$ f(x) = |x| $$ where |x| denotes the absolute value ofx. DescriptionThe absolute value function is significant in mathematics because it measures the distance of a number from zero on the number line, regardless of direction. This function is linear in nature, as it can be broken into two linear pieces: one for $$ x \geq 0 $$ and one for $$ x < 0 $$ |

Definition--Functions and Relations Concepts--Composite Function | Composite FunctionTopicFunctions and Relations DefinitionA composite function is a function that is formed when one function is applied to the result of another function. DescriptionComposite functions are significant in mathematics because they allow the combination of two functions to form a new function. This is denoted as (f∘g)(x) = f(g(x)). Composite functions are widely used in various fields, including computer science for function composition in programming and in calculus for chain rule applications. For example, if f(x) = 2x and g(x) = x + 3, then the composite function (f∘g)(x) = f(g(x)) = 2(x + 3) = 2x+6 |
