   : View Source, ShowAbout bperkhou: I am a student at Stanford University. In this video lessons, I show how to approach quadratic inequalities graphically. If you have a quadratic inequality, you can graph the quadratic function on the coordinate plane. For this quadratic to be greater than zero or less than zero, it has to be the portion of the graph which is above or below the x-axis respectively. So you can use this to find the solution to the inequality. For more details on how this works, look at the video! This lesson has been accessed 6274 times. |
