Again, we can use the vertex to find the maximum or the minimum values, and roots to find solutions to quadratics. This can be done by looking at the general form of a quadratic equation: $ \displaystyle y=ax^2+bx+c$. We need to solve for a,b and c in order to write our equation and we have three points so we can do this through substitution. First use (0,-4) for (x,y) and you get $ \displaystyle -4=a(0)^2+b(0)+c$ which means that c=-4. The graph of a quadratic equation is called a parabola. If a > 0, then its vertex points down: If a < 0, then its vertex points up: If a = 0 the graph is not a parabola and a straight line. The vertex of the parabola is at the point. x = − b 2 a \displaystyle x = -\frac {b} {2a} Vieta's formulas. If x1 and x2 are the roots of the quadratic ...
