Find the vertex and axis of symmetry of the graph of the function
f(x) = 3x^2 - 2x + 5
----------------------------
3(x^2 - (2/3)x + ?) = y - 5 + 3*?
---------------------
3(x^2 - (2/3)x + (1/3)^2) = y - 5 + 3(1/3)^2
3(x-(1/3))^2 = y - (14/3)
-----
Vertex: (1/3 , 14/3)
----
Axis of symmetry: x = 1/3
