Question 2(Multiple Choice Worth 1 points)
(08.02 MC)
The function f(t) = 4t2 β 8t + 7 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 β h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t).
f(t) = 4(t β 1)2 + 3; the minimum height of the roller coaster is 3 meters from the ground
f(t) = 4(t β 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground
f(t) = 4(t β 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
f(t) = 4(t β 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground
