red line under the green line what does it mean ?

[@manhattanprepgre7390]

Hi, Rituraj!
It sounds like you're referring to the solution to question 7 at 55:24. In this solution, the red line represents y = x, and the green line represents y = x|x| . Next, examine any vertical "slice" of these graphs: any place where the red line is under the green line represents a point where x < x|x| . And expanding this thinking to ranges, the red line is under the green line for values where x > 1, and values where -1 < x < 0 . In other words, if it is true that x < x|x|, then the only valid ranges for x are x > 1, or -1 < x < 0
