(on the comparison of positive scale function and inverse scale function) It is known that in the same rectangular coordinate system, the positive scale function y = - 3x and the inverse scale function y = - 6 / X (this is a fraction, you should understand ~) intersect two points P and m below the x-axis, point a is on the negative half axis of the x-axis, and the distance from the origin is 4, Find: (1) the coordinates of P and m (2) Area of triangle map Depressed ……
How is it possible that the image intersects P and M points below the x-axis
（1）
Substituting y = - 3x into y = - 6 / X yields - 3x = - 6 / X
x^2=2 x=±√2
We can get the coordinates of two intersections: P (√ 2, - 3 √ 2); m (√ 2,3 √ 2)
（2）
Area of triangle map = (4 * 3 √ 2 + 4 * 3 √ 2) / 2 = 12 √ 2

- 15. The concept of inverse proportion function~ We know the general form of y = K / X inverse scale function. Then, y = K / 2x is also an inverse scale function. In the inverse scale function of y = K / 2x, if you know that point a (5,6) is on the function image, you need to substitute the coordinates of point a into the function. At this time, is y = 6, x = 5 or 2x = 5?

- 19. On the concept of inverse proportional function It is said in the book that a function in the form of y = K / X (x ≠ 0, y ≠ 0, K ≠ 0) is called an inverse proportion function But, why do I do a question in the exam, say: y = k-1 / x, when k-1 why value, y = 0? Then this is not an inverse proportion function... Who can tell me what's going on... T t =Why do you go to k-1? My question is: concept (x ≠ 0, y ≠ 0, K ≠ 0), but the question is (forget it, just K, lest you misunderstand it.) why is k worth y = 0
