Quadratic Functions Exercise 2 - Using the Vertex Formula

Given that  f(x) = 2x2 - 3x + 1, find the vertex using the Vertex Formula for Quadratics in the Form y=ax2+bx+c .  Then graph f(x). The justification is already given in this exercise.
 

STATEMENT JUSTIFICATION
f(x) = 2x2 - 3x + 1 Given

Graphs of the form
 f(x) = ax2 + bx + c have a vertex at (-b/(2a), f(-b/(2a)) and have the same shape as y=ax2.
