The function f(t) = 4t2 − 8t + 6 shows the height from the ground f(t), in meters, of a roller coaster car at different times t. Write f(t) in the vertex form a(x − h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t).
A. f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 3 meters from the ground
B. f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground
C. f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
D. f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground
