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 x-intercept 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)

First take. -16 out -16(t^2+2t-8) Can you factor this?

I have no clue how to do any of this...

This 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
welshfella
  • welshfella
* solve for t
nincompoop
  • nincompoop
well let us understand what the equation meant first

solving for t, or anything is pretty useless if you do not understand what it is

wait so I substitute the 0 for t?

The 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|

You are being asked to factor the function \(f(x) = -16t^2 - 32t + 128 \) and was asked to interpret the x-intercepts. 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|

The x-intercept in a quadratic equation is the location where the graph intercepts the x-axis. If you look closely, the value of y in the x-axis is zero.

The x-intercept in a quadratic equation is the location where the graph intercepts the x-axis. If you look closely, the value of y in the x-axis 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|
