Friend, I know your question is not clear, so look at your own test paper and see what I said:

The linear function of (1) is y=x+b, and the inverse proportional function is y= 1/x, so the simultaneous formula shows that the intersection point is A(-b+√b? +4/2, 1/-b+√b? +4/2),B(-b-√b? +4/2, 1/-b-√b? +4/2)。

(2) The value of the original function is smaller than that of the inverse proportional function, and the range is between AB points, so it is (-b-√b? +4/2,-b+√b? +4/2)。

Just bring the test paper directly when you see it. If you don't understand, ask me. I will be more specific. I wish you progress in your study!
