Page 1: Introduction to Linear Functions
This page introduces the fundamental concepts of funkcja liniowa linearfunction. It explains the general form of a linear function and its key properties.
The general form of a linear function is presented as fx = ax + b or y = ax + b, where:
- 'a' is the slope or współczynnik kierunkowy funkcji liniowej gradientofthelinearfunction
- 'b' is the y-intercept
The page outlines the behavior of linear functions based on the value of 'a':
- When a > 0, the function is increasing
- When a < 0, the function is decreasing
- When a = 0, the function is constant
Definition: A linear function is a function whose graph is a straight line, represented by the equation fx = ax + b.
Highlight: The slope 'a' determines whether the function is increasing, decreasing, or constant.
Example: For the function fx = 2x + 3, 'a' is 2 positive, so the function is increasing.
The page also introduces the concept of miejsce zerowe funkcji liniowej zeroofthelinearfunction, which is the x-intercept of the function.
