 * we are:**

c=20
=== Because A is -16 then the parabola will be a maximum, meaning that it will open downward.The magnitude has to do with size. Since there are no fractions then we know the magnitude in our equation will be a bigger height. The variable 'c' determines the width, so since c=20 then the parabola will be wider than a if the variable equaled a number less than 20. ===

The discriminant is the part of the quadratic equation in the square root. To solve the discriminant you need to:

 * 1) Determine the variables
 * 2) Solve the exponent
 * 3) Multiply 4, 'a,' and 'c'
 * 4) Add

==

**The solution to the discriminant is a positive 1280, and the discriminant determines the number of roots so we know there will two roots on the X Axis.**
**__The Math__:** Pretend you are the teacher, and this section is your lesson. Post the calculations required to graph the equation and find the solution, and show all the steps to doing so. Teach your audience all the important parts of the graph and explain that they mean for the problem you were given.

To find the Vertex:

 * 1) Plug in the AOS to the 't'
 * 2) Multiply
 * 3) Add
 * 4) The answer will be used as the starting point of the parabola on the AOS

The axis of symmetry for our equation was 0, and then we used the Axis to find the vertex which was 20.
=== The best way to solve for 'x' is to graph the parabola with the coordinates we got from the axis of symmetry and vertex. The roots that we got were identical to the roots found on the parabola, so graphing was the best way to solve for 'x.' ===

-The solution to our vertical motion problem signifies how long the object took to hit the water, which was about 1.12 seconds because you can't go back in time.
=== -The vertex represents the point where the object is dropped, because the vertex is the highest point where the stone is dropped, which is at the coordinate (0,20). Zero represents the starting time and 20 represents the starting height. ===

-The object is in air 1.12 seconds, and we know this because when the object was dropped it took 1.12 seconds from 0 to get to the roots. Also, because we can't go back in time.

 * __Reflection__** How did it feel to do the work and pretend to be the teacher? Do you think you understand the material more, now? Why or why not?

=== **__Allie:__** The thing that was hard for me was the graph. If i could re-do the project I would probably work harder on the project. Doing this project did help me on this, because we had to keep doing it in the project, and as a group. It was easy to do the work because Diana understood how to do it so, she helped me out. Being recorder was pretty easy. I had to keep the papers when we left 5th period and keep them from getting ruined. ===

=== **__ Elexis: __** I thought finding the parabola was hard. I think this because I had to keep up with the number cruncher and the recorder who didn't have the equation done! Being the facilitator was hard in many ways. ===

=== **__Diana:__** What I thought was difficult was finding the parabola. I thought this because i didn't have the equation with me so i had to rethink with my group. I actually understood more after this project because i had help with it. Being the number cruncher is annoying because the group depended on me to find the equation which i didn't have. ===
