Integrated math 2- PRBL 2.7.1 Fallen Keys
What were the problems?
The prompt in this problem was, Piper drops her keys from a third-story window to a friend standing on the sidewalk. The distance between the keys and the ground, in feet, can be represented by the function f(x)=-16x^2+32, where x is the time in seconds. Piper would like to be able to determine the time, in seconds, at which the keys were any given distance from the ground. What is the function with height in feet from the ground as the independent variable? After about how many seconds were the keys 4 feet above the ground? The prompt was asking me for the seconds in which the keys fell 4 feet above the ground.
-What I was suppose to do here was a PRBL it's a sheet of paper the teacher gives us every time we do a new lesson
-I was suppose to solve the equation f(x)=-16x^2+32.
-This equation that was given to me was a Quadratic one because it has a -16.
-Change from restricted form to inverse form
-Algebraic form is f-1(x)= the square root of x over 16+2

Knowledge and thinking
Something I learned in this project was how to solve an equation by going from restricted to inverse that way I could continue with the problem. Another thing I learned in this project what a quadratic equation meant and how to solve it. One last thing I learned was that I have to change the negative to a positive because in real life you can't use negative numbers.
Agency
After doing this sheet of work my agency grew more. I think this PRBL was one of all of the other ones the one I really understood and did it myself. Whenever we used to do I used to ask for help to my teammates and I would take the whole time in the table just trying to figure out what to exactly do. I also learned what quadratic meant. But overall I learned how to do this problem that has many steps to it.
How I took Ownership over my learning?
- How I took ownership over my learning was by doing this worksheet by my self and understanding the lesson.
- Stayed focused
- Made sure I was getting the answer correctly by asking classmates
