Exercise: Week 8 Concept Check Due Day 5 (Friday) Post in the Assignment Section a response to the following: If you are looking at a graph of a quadratic equation, how do you determine where the solutions are? any point on the graph is a solution of the equation of that graph. example: if your equation is y = x^2 + + x + 1, then when you look at the graph and see a point on the graph, you plot what the x value of that point is and the y value of that point is and you have a solution of the graph. ----- if it is a quadratic equation, where the graph crosses the x axis tells you what the roots are of the equation. these are called the x intercepts. if the graph doesn't cross the x-axis then it doesn't have any real roots. since a quadratic is in the form of ax^2 + bx + c, then a, b, and c tell you a few things about the graph also. -b/2a is the x value of the minimum / maximum point on the graph. if the graph is pointing upwards, then -b/2a is the x value of a maximum point.
