Consider function y=f(x)=a/x. This is so-called rectangular hyperbola. Simple calculation shows that the derivative of y with respect to x is -a/x^2. According to the definition of elasticity, the elasticity of y with respect to x is (dy/dx)*(x/y)=-1. If one regard the function as demand function (in this case, the restriction a>0 should be imposed), and take absolute value of the above definition of elasticity, then demand elasticity is always 1.
