Definition. Schematic depiction of a function described metaphorically as a "machine" or "black box" that for each input yields a corresponding output. The red curve is the graph of a function, because any vertical line has exactly one crossing point with the curve.
A function relates an input to an output, and has special rules of covering every element and being single valued. Learn how to write, name, and graph functions with examples and sets.
College of the Redwoods. Our development of the function concept is a modern one, but quite quick, particularly in light of the fact that today’s definition took over 300 years to reach its present state. We begin with the definition of a relation.
22 paź 2024 · function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
