This is the Reciprocal Function:
f(x) = 1/x
This is its graph:
It is a Hyperbola.
It is an odd function.
Its Domain is the Real Numbers, except 0, because 1/0 is undefined.
Using set-builder notation:
Its Domain is {x | x ≠ 0}
Its Range is also {x | x ≠ 0}
The Reciprocal Function can also be written as an exponent:
f(x) = x-1
