Funktioarvoa refers to the output of a mathematical function for a specific input. When a function is defined, it establishes a relationship between a set of possible inputs, known as the domain, and a set of possible outputs, known as the codomain. For any given value within the domain, the function assigns a unique corresponding value in the codomain. This assigned value is called the function value.

To find the function value, one substitutes the specific input value into the function's expression or rule. The result of this evaluation is the function value. For instance, if we have a function f(x) = x^2, and we want to find the function value when x = 3, we substitute 3 for x, resulting in f(3) = 3^2 = 9. Therefore, the function value of f(x) at x=3 is 9.

The concept of function values is fundamental in mathematics and is used across various branches, including algebra, calculus, and statistics. Understanding function values allows us to analyze the behavior of functions, solve equations, and model real-world phenomena. Each point on the graph of a function represents an input-output pair, where the y-coordinate is the function value corresponding to the x-coordinate, which is the input.
