Función real

"Función real," or real function, refers to a mathematical relationship where each input (or variable) from a set of real numbers corresponds to exactly one output from another set of real numbers. Essentially, think of it as a machine: you input a number, and the machine processes it to give you one specific number as the result. This concept is fundamental in calculus and algebra, helping in understanding how quantities relate to each other, and it is used in various fields such as science, engineering, and economics to model real-world phenomena.
