• 8. 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?
