Question

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.
