Whoops, you're right, I brain farted the wrong word. To be clear, though, they were still wrong. `f(x)=2x` has the property they described of consistently giving the same input for a given input (if you pass in 1, it will always output 2), but it is not idempotent because f(f(x)) does not, in general, equal f(x). |
