függvényértéknek

Függvényértéknek is a Hungarian term that translates to "function value" in English. It refers to the output of a function for a specific input. When a function is applied to an element from its domain, the result is the function value. For instance, if we have a function f(x) = x^2, and we input the value 3, the function value is f(3) = 3^2 = 9. This concept is fundamental in mathematics and computer science, as functions are used to describe relationships between sets of data or to perform computations. The set of all possible function values for a given function is called its range. Understanding function values is crucial for analyzing the behavior of functions, solving equations, and developing algorithms. The notation f(x) is commonly used to represent the function value of f at the input x.
