WebStep 1: Enter the function below for which you want to find the inverse. The inverse function calculator finds the inverse of the given function. If f (x) f ( x) is a given function, then the inverse of the function is calculated by interchanging the variables and expressing x as a function of y i.e. x = f (y) x = f ( y). Step 2: WebDirect Proportion. With direct proportion, the two variable change at the same time. In direct proportion, as the first variable increases (decreases), the second variable also increases (decreases). In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x ...
