Example 2: Graphing Quadratic Functions in Standard FormConsider the function f(x) = x2 ­ 4x + 6a.  Determine whether the graph opens upward or downward.

b.  Find the axis of symmetry.

c.  Find the vertex.

d.  Find the y­intercept.

e. Graph the function.

Extra Example 2: Answer a ­ e also for f(x) = ­4x2 ­ 12x ­ 3.
