Check of oddity for a linear function y=kx+b, b=0 returns false when k≠1, even though all linear functions passing through (0,0) are odd:

IsOddFunction(x,x) True IsOddFunction(2*x,x) False

This doesn't affect y=k/x functions, however:

IsOddFunction(1/x,x) True IsOddFunction(2/x,x) True IsOddFunction(2*1/x,x) True

Applicable to both yacas online and Ryacas 1.1.3.1.
