When doing quadratic Inequalities, how would you know to write y<x<z or x<z or x>y.
Sometimes in questions I get confused between which I should write.

It helps if you imagine the graph. If all of the points are above the line, then it would be y > *quadratic equations*, if the points are below the line then it's y < *quadratic equation*
