Summary of Mathematics Knowledge Points in Senior High School Entrance Examination: Concepts of Linear Function, Proportional Function and Linear Function
Generally speaking, if (k, b is a constant, k0), then y is called a linear function of x.
Especially when b in the linear function is 0, (k is a constant, k0). At this time, y is called the proportional function of X.
Description: The relationship between the position of a straight line and a constant.
Linear function image
All images of linear functions are linear resolution functions.
Increase and decrease of the range of independent variable values of images
Proportional function
All real numbers
(1) when k >; 0, y increases with the increase of x;
2 when k >; & lt0, y decreases with the increase of x.
