Remember how the discriminant determines the number of solutions of a quadratic equation? You can start by finding the xintercepts, if there are any That is when y = 0 0 = x^2 4x 5 0 = (x 5)(x 1) So you have one intercept at x = 5 and one at x = 1 Or, at "(5, 0)" and "(1, 0)" Then, you can find where the vertex is (where the graph turns around) This can be found using x = (b)/(2a) ((4))/(2*1) = 4/2 = 2 Then you can plug it into the original equation3 Graph each quadratic function and identify the characteristics below 11 y = –(x 3)2 4 12 y = x2 – 2x – 3 Vertex Vertex x Intercepts Axis of Symmetry
