Final Paper

The final paper should include all they have discovered in the previous week. I want all of their information here. They then should go on to answer the bus problem.

We can see this problem is not linear, exponential, or quadratic. When we graph this situation we get a graph that looks like it might be exponential decay but there is another copy of the graph in quadrant 3. This makes it not exponential. We can see that if I multiply the rate and the time the distance is always 5000 so the equation is 5000/r=t. Anytime we divide by a variable (r) we get an inverse relationship. Inverse relationships are the opposite of linear equations that go through (0,0).
