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).

f (t) = 4 (t - 1) 2 + 3; the minimum height of the roller coaster is 3 meters from the ground

f (t) = 4 (t - 1) 2 + 3; the minimum height of the roller coaster is 1 meter from the ground

f (t) = 4 (t - 1) 2 + 2; the minimum height of the roller coaster is 2 meters from the ground

f (t) = 4 (t - 1) 2 + 2; the minimum height of the roller coaster is 1 meter from the ground
