How do you know if #h(x) = x / (x^2 - 1)# is an even or odd function?

Examine #h(-x)# to see that #h(x)# is an odd function.

Explanation:

A function #f(x)# is even if #f(-x) = f(x)#.
A function #f(x)# is odd if #f(-x) = -f(x)#

Then, to see if #h(x)# is even or odd, we examine #h(-x)#.

#h(-x) = (-x)/((-x)^2-1)#

#= -x/(x^2-1)#

#= -h(x)#

Thus #h(x)# is odd.
