As you learned in Chapter 4, the graphs of all quadratic functions have a line of symmetry that contains the vertex and divides the parabola into mirror-image halves. Consider this table of values generated by a quadratic function.

a. What is the line of symmetry for the graph of this quadratic function?
b. The vertex of a parabola represents either the maximum or minimum value of the quadratic function. Name the vertex of this function and determine whether it is a maximum or minimum.
c. Use the table of values to write the quadratic function in vertex form.
