Can someone help I will give medal I don't not understand how to do this
A sandbag was thrown downward from a building. The function f(t) = 16t2  32t + 384 shows the height f(t), in feet, of the sandbag after t seconds:
Part A: Factor the function f(t) and use the factors to interpret the meaning of the xintercept of the function. (4 points)
Part B: Complete the square of the expression for f(x) to determine the vertex of the graph of f(x). Would this be a maximum or minimum on the graph? (4 points)
Part C: Use your answer in part B to determine the axis of symmetry for f(x)? (2 points)

Best ResponseYou've already chosen the best response.1Part A start here \(\large f(t) = 16t^2  32t + 384 = 16(t^2 +2t  24) \) now make it \(\large f(t) = 16(ta)(tb) \) ie factor it. x = a and x = b are where f(t) = 0.

Best ResponseYou've already chosen the best response.0Do I factor 16 with (ta)(tb)?

Best ResponseYou've already chosen the best response.1a made up example: \(\large f(t) =  15 (t^2 + t  6) = 15(t2)(t+3)\) so, in our example, we know that f(t) = 0 at t = 2 and t = 3 [ or f(2) = f(3) = 0 ] it will hit the ground at t = 2. t = 3 is something that existed before it was dropped and we can guess that it would have taken 3 second to have risen to its drop height at t = 0. if that makes sense :p

Best ResponseYou've already chosen the best response.1so you have to do that for the actual question above pattern match with the example if need be
