X 2 4x 6 = 0 Step 2 Parabola, Finding the Vertex 21 Find the Vertex of y = x 24x6 Parabolas have a highest or a lowest point called the Vertex Our parabola opens up and accordingly has a lowest point (AKA absolute minimum)The vertex form of a quadratic is given by y = a(x – h) 2 k, where (h, k) is the vertex The "a" in the vertex form is the same "a" as in y = ax 2 bx c (that is, both a's have exactly the same value) The sign on "a" tells you whether the quadratic opens up or opens downWrite the equation y = x^2 4x 12 in vertex form Sketch the graph of the equation y = x^2 4x 12 Sketch the graph of the equation 4y = 4 x^2 Determine the focus and directrix of this parabola Match the equations to the graphs i y = x^3 ii y = 3 3x^2 x^3 iii y = 3x(x^2 1)
