The image of positive scale function y = KX (k is constant, K < 0) passes through the second step______ Quadrant, function value increases with the increase of independent variable______ .

The image of positive scale function y = KX (k is constant, K < 0) passes through the second step______ Quadrant, function value increases with the increase of independent variable______ .


The positive proportion function y = KX, ∵ K < 0, ∵ image successively passes through the second and fourth quadrants. According to the image property of the function, the value of the function decreases with the increase of the independent variable. Therefore, the answer is: two, four, decrease



In the positive proportion function y = KX + B, when k > 0, what is the relationship between Y and X? When k = 0, what is the relationship between Y and X?


When k > 0, y value increases with the increase of x value
When k < 0, y value decreases with the increase of x value
When k = 0, y = B has nothing to do with X
