How am I supposed to graph y = 2/x? Which values should I use? (This is supposed to be an inverse variation graph.)

when x = 0, undefined (very big to the right, very negative to the left of origin)
when x = 1, y = 2
when x = -1, y = -2

when x = 2, y = 1
when x = -2, y = -1

when x = 5218575, y is very close to x axis above it
when x = -5218575, y is very close to the x axis under it.

you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. use this information to write a linear equation that gives the dollar value v of the product in terms of the year. (let=12 represent 2013) 2012 rate and 156 4.50 increase per year
