Variation Functions

1. Direct

   • • n=1
       • Line
         • Domain and Range"
     • n=2

2. Inverse

3. Fundamental Theorem of Variation

   • When x is multiplied by a constant, the change in y is predicted. If y varies directly as xn, then when x is multiplied by c, y is multiplied by cn.

4. Converse of the Theorem of Variation

   • If y varies inversely as xn, then when x is multiplied by c, y is divided by cn
