In Analyzing the Graphs of Quadratic Functions, our instructor begins with the vertex form and the axis of symmetry and vertex built into the formula. Then they cover the significance of the coefficient 'a' as well as how to write quadratic equations in vertex form. Finally are the four examples at the end.
Know and understand the vertex form of a quadratic function.
The coefficient of the quadratic term determines the direction that the graph opens and the shape of the parabola.
The values of h and k in the vertex form determine how the graph is translated vertically and horizontally.
Complete the square to put a quadratic function in vertex form. Factor the coefficient of the quadratic term first if it is not 1.
