Equations of Quadratic Functions Applications 12. I can use the discriminant to determine the number and type of solutions/zeros. I. I can identify a function as quadratic given a table, equation, or graph. 2. I can determine the appropriate domain and range of a quadratic equation or event. 3. Complex solutions to quadratic equations. Given a quadratic equation \(ax^2+bx+c=0\) the quadratic formula gives the two solutions \[ x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} \] You may recall that the quantity \(b^2-4ac\) is called the discriminant, because we can discover certain facts about the solutions based upon its value.

 Recall that a, b > 0 and c < 0. For our final equation -a = A < 0, 1 = C > 0, and b-2ac = B > 0, therefore the x-coordinate of our vertex lies on the left side of the y-axis. Now, our discriminant for the final equation is B²-4AC, which is greater than zero since -4AC > 0. It follows that the final equation satisfies our claim. A quadratic equation has a discriminant of 12. Which could be the equation? 1.) 0 = –x2 + 8x + 2. 2.) 0 = 2x2 + 6x + 3. 3.) 0 = –x2 + 4x + 1. 4.) 0 = 4x2 + 2x + 1.
