A sandbag was thrown downward from a building. The function f(t) = 16t2  32t + 128 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.1This factors to the from 16(t+a)(t+b) And to get the x intercepts equate to zero and sovereign for t One of these values of t will be the times when height is zero

Best ResponseYou've already chosen the best response.0The function \(f(x) = ax^2 + bx + c \) gives you a general clue about the location or position of the object that is you are working on. The c in the function tells you how high or how far you are starting from. dw:1434219502610:dw

Best ResponseYou've already chosen the best response.0You are being asked to factor the function \(f(x) = 16t^2  32t + 128 \) and was asked to interpret the xintercepts. But before you jump into factoring it, you need to remember the general graph for a quadratic equation. It is called a quadratic equation because the highest exponent is 2. dw:1434219835751:dw

Best ResponseYou've already chosen the best response.0The xintercept in a quadratic equation is the location where the graph intercepts the xaxis. If you look closely, the value of y in the xaxis is zero.

Best ResponseYou've already chosen the best response.0The xintercept in a quadratic equation is the location where the graph intercepts the xaxis. If you look closely, the value of y in the xaxis is zero. And if we interpret this into falling object from a particular height or object thrown from the ground, the intercepts are the zeroes  one of them is where you started. if you make t equals to zero \(f(t) = 16t^2  32t + 128 \) you will get what I told you in the beginning  the position function, that is where your object is. dw:1434220223115:dw
