Is #c = 3v# a direct variation, inverse variation, or neither?
In a direct variation, one number changes based on how the other changes. Basically, some number
In an inverse variation, two numbers change so that their product will stay constant. Unlike a direct variation, one number gets bigger while the other gets smaller. This is usually written as:
Now look at the original equation:
We can see that
This is also an equation of the form
So, this is a direct variation.
