The vertex form of a parabola s equation is generally expressed as y a x h 2 k h k is the vertex as you can see in the picture below If a is positive then the parabola opens upwards like a regular U If a is negative then the If a 0 the parabola opens downward and the vertex is a maximum Figure 5 2 5 represents the graph of the quadratic function written in standard form as y 3 x 2 2 4 Since x h x 2 in this example h 2 In this form a 3 h 2 and k 4 Because a 0 the parabola opens downward
