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
* solve for t
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|

This is a Q on a test.
We help you study FOR tests… not ON the test.
do you have a proof that this is from an exam that he/she is taking now?
I have proof
So do I.
then report the person to the school.
ITS AN online course
Known as florida virtual school
We don't know the identity of this person… so we can't report it.
I understand that you dont understand the question but you can't be asking that on here. Since its a test question
Or Quiz question
well I have not given any answer. everything has just been a general description, and I just used the height as an example.
@nincompoop Keep helping him/her
Just dont give a direct answer
I will be back later. you can argue with the person while I eat
If you see the date (5/1/15) I'm not making this up.
You just mentioned test towards the end.
"(4 points)" ok.
