Analyzing the Graphs of Quadratic Functions

• 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.
