Linear functions are fundamental in mathematics, describing relationships where one variable changes at a constant rate with respect to another. This summary explores key concepts, formulas, and properties of linear functions, providing essential insights for students studying algebra and graphing.
- Funkcja liniowa (linear function) is defined by the equation f(x) = ax + b, where 'a' is the slope and 'b' is the y-intercept.
- The behavior of a linear function depends on its slope: it increases when a > 0, decreases when a < 0, and remains constant when a = 0.
- Understanding własności funkcji liniowej (properties of linear functions) is crucial for solving related problems and interpreting graphs.
