Final answer:
In the context of the inverse function, x represents the input variable and c-1(x) represents the output variable.
Step-by-step explanation:
In the context of the inverse function, x represents the input variable and c-1(x) represents the output variable.
The inverse function undoes the actions of the original function. So, if the original function transforms x into y, then the inverse function transforms y back into x.
For example, if we have a function f(x) = 2x, the inverse function would be f-1(x) = x/2. So, in this case, x would be the input variable and f-1(x) (which is actually equal to x/2) would be the output variable.
