How to learn mathematics elective 1-2 in senior two? Chapter 1. Regression analysis

As long as you listen carefully in class, do your homework in time after class, ask the teacher about the questions you don't understand or send them to ask. In fact, you need to have confidence. Come on

Given proposition p: x + 1 / x-3 is greater than or equal to 0; Q: absolute value 1-x / 2 < 1, if P is true proposition and Q is false proposition, find the value range of real number X

Because P is a true proposition, it satisfies x + 1 / x-3 > = 0,
Because q is a false proposition, it satisfies | 1-x / 2 | > = 1
