The definition of inverse proportion function The y of inverse proportion function must decrease with the increase of X or increase with the decrease of X

Not necessarily. When k is less than 0,
When y = K / X (k is constant and K ≠ 0), the function is called inverse proportional function

2. 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?

12. 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
