Let’s think about the graph of the equation y=2/x. 1. make a table of (x, y) pairs that will help you graph the equation. make sure to include some negative number for x and some numbers that are not integers.

2. plot the graph on the coordinates axes. you may need to find a few more points to plot to make the graph look smooth.

3. The coordinate plane provided is too small to show the whole graph. what do you think the graph looks like when x is between 0 and 1/2? try some values of x to test your idea.

4. what is the largest value that y can ever be?

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
