**__The Word Problem__:** How would you solve for time in the problem your group was assigned? Prepare the equation to solve for time, defining the variables and supporting your choice in equation. ======

**4.**

**__The Parabola:__** Use what you know about parabolas to predict the shape of the graph. What will it look like, and how do you know? 1. a= -16, b=0, c=20 2. When a is -16, the negative makes the vertex a maximum and whole number makes it narrow. 3. C makes the vertex shift up or down on the y-axis so it would be at (0,20). C is the y-intercept. 4. The discriminant is what tells you if the expression has two solutions, one solutions, or no solutions. This discriminant is positive so it has two solutions.

==**__// 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 what they mean for the problem you were given. == The equation above is the equation for the axis of symmetry is x= -b/2a 1. x is the vertex and the axis of symmetry.

**__The Solution and The Meaning__: What do the different parts of the graph mean? What does the solution mean? **
=== **1.) There are two solutions 1.1 seconds and -1.1 seconds, but the rock can't drop at a negative time so only 1.1 seconds makes sense. If the answer was negative the rock would be going backwards in time.** ===

**5.) 1.1 seconds because that's how long it was in the air before the rock hit the water**.
+5/5

**__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?
Fatima--> I found part 3 hard because we couldn't figure out the roots. I would have been less frustrated at my group. Yes, it helped now I remember the roots are where the x and y axis cross, also that the vertex is the starting height. I didn't realize it was so much work but it was fun. I liked using Math Type.

Judy--> I found part 4 hard because it is asking what the vertex, roots and y-intercept represent and it was hard to figure out. I would use my notes more. Yes, because it helped me learn what the vertex, roots, and y-intercept represent. Being a teacher is hard, but I think its fun because of the computer work.

Cynthia--> I think part 2 was hard because the problem was that we had to do the Quadratic formula and solve for t. I think next time I would have better notes and to be more focused on the work. Yes, the project helped me understand the Quadratic formula better because my partners were able to show me how to work out the problem. Being the teacher was sort of hard and I didn't even understand how to do much untill I got help.
