If #xy = −25# what is the constant of variation for this relationship?

Answer 1

The constant of variation is #-25# and the relationship is one of inverse variation

The constant of variation is the number that relates two variables.

To know what the constant of variation is, you first have to identify what type of variation is occurring: direct or inverse.

The formula for direct variation is: #y = kx#
The formula for inverse variation is: #xy = k#

Since the question matches for formula for inverse variation, we know that that's the type of relationship. In both equations, k is the constant of variation.

So it's important to identify the type of variation and the value of k in order to understand the relationship.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
