More About Reciprocal Functions

A reciprocal function has a domain and range of all real numbers. The domain and range for both is negative infinity to positive infinity. The reciprocal functions do not intercept with anything. It decreases from negative infinity to zero and again from zero to infinity. The reciprocal function is an odd function. Its' symmetry is of the origin. It also has a vertical asymptote on the y-axis and a horizontal asymptote along the x-axis.
