Back

Inverse variation describes a relationship between two variables where the product of the variables is constant. If one variable increases, the other decreases.

Front

What does the constant k represent in inverse variation?

Back

The constant k represents the product of the two variables in an inverse variation relationship.

If x = 5 and y = 20, what is the constant k?

Back

k = 5 * 20 = 100.

Front

What values are excluded from the domain of an inverse variation function?

Back

The value x = 0 is excluded from the domain because it would make the function undefined.
