Determine the vertex of the function f(x) = 3x2 – 6x + 13.
 1. Identify the values of a and b. 
 a = and b =
 2. Find the x-coordinate of the vertex.
 negative StartFraction b Over 2 a EndFraction =
 3. Find the y-coordinate by evaluating the function at the x-value found in the previous step.
 The vertex is.
