Curves: reciprocal
Choose values for a and observe the values of

y = a/x

a =              
x -5 -4 -3 -2 -1 0 1 2 3 4 5
a/x

Why does the table show either "NaN" or "Infinity" when x=0?


Here is a plot of some points from a reciprocal equation.


Here you can move the point with your mouse (right-click to clear) and observe how the coordinates change. What is the equation that matches this graph?
a1 a2 a3 a4
b1 b2 b3 b4
c1 c2 c3 c4
