Question
Can zero be in the domain of an inverse variation?
Hint:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
The correct answer is: No
Inverse variation is modeled by the equation y = 
.
If x = 0, y is undefined.
So, x cannot be equal to 0.
Thus, zero can’t be in the domain of an inverse variation.
The product of any number with 0 is always 0. So, zero cannot be the domain of an inverse function.
