Function Notation
In mathematics, equations that define functions are often written using function notation. Functions are typically assigned single-letter names, most commonly , , , , , or . For a function named , the notation specifies the relationship between an input value and its corresponding output value as . In this notation, represents the domain value, and represents the corresponding range value. The expression is read as ' of ' or 'the value of at '. The parentheses in this context indicate the input parameter mapping to the function and do not indicate multiplication.
