Well, I don't know that it's "despicable" jargon (this is the kind of statement that discourages people from being comfortable with mathematics and it worried me that a mathematical term was being maligned, so I read.

An exponential decay (increasing form) curve describes situations where a quantity grows quickly at first, then levels out to some limiting value.

The actual choice for their example was unfortunate, because the variables seemed to have nothing to do with economics (they don't and I was no wiser about what was going.
