Zero cannot be in the domain of an inverse variation [tex]\boldsymbol{y=\frac{k}{x}}[/tex] as [tex]\frac{k}{0}[/tex] is undefined.
The domain of a function is the set of inputs accepted by the function.
An inverse variation is a mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
Inverse variation means [tex]\boldsymbol{y=\frac{k}{x}}[/tex]
Here, [tex]\frac{k}{0}[/tex] is not defined.
So, zero cannot be in the domain of an inverse variation.
