Answer: The answer is NOT letter B or letter C

D. y = 1/3x^2 - x + 2

Step-by-step explanation:

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Up

Vertex:  ( 3 /2 ,  5 /4 )

Focus:  ( 3 /2 ,  2 )

Axis of Symmetry:  x = 3 /2

Directrix:  y = 1 /2

x                 y

0                2

1                 4 /3

3 /2             5 /4

3                 2

4                10 /3
