WebAn inverse variation occurs if one of the variables increases or decreases and the other variable decreases or increases. It can be read as “varies inversely” and “inverse proportion”. Inverse variation exists if the relationship exists between the two variables whose product is constant (k). Example: WebAs she sets out cups, spoons, and plates, Isabel’s doubts grow. She looks around, trying to imagine what else she could do to make the cafe perfect, but nothing comes to mind. Then, in a sudden burst of inspiration, Isabel grabs her paintbrush and transforms the blank walls into landscapes, adding flowers and trees.
