If f(x) = 2x2 – 8x + 9, which statement regarding the vertex form of f(x) is true? A. In vertex form, f(x) = 2(x - 2)2 +1 and therefore has a minimum value of 1.
B. In vertex form, f(x) = 2(x - 2)2 + 1 and therefore has a minimum value of 2.
C. In vertex form, f(x) = 2(x - 2)2 + 4.5 and therefore has a minimum value of 4.5.
D. In vertex form, f(x) = 2(x - 2)2 + 4.5 and therefore has a minimum value of 2.
