For each quadratic function below, complete the square to write it in graphing form. Then state the vertex of each parabola.
Draw tiles to help you make the expression into a square.
Put it into graphing form and from there figure out the vertex.
See part (a).
On each graph, does the vertex represent the maximum or minimum value of the parabola?
Is the vertex the highest (maximum) or lowest (minimum) point on the graph?
