Adjective edit

- 2013, Yvelyne Germain-McCarthy, Bringing the NCTM Standards to Life: Best Practices, High School, page 101:
- ... Students apply the definition of slope to various representations of growth functions to discover differences between exponential and constant rate of growth.
- 2018 July 31, Alvin Carpio, “Is it time to automate politicians?”, in The Economist:
- Of course, one can creatively conjure up a host of things robot-politicians can do at exponential speed and scale, from shaking hands and kissing babies to handling the fundraising “robocalls” that frustrate American voters.
Usage notes edit
- In non-technical contexts, the term is sometimes used loosely to refer to any kind of very rapid change, especially increase. This usage is often discouraged unless the change in question is truly exponential; synonyms such as dramatic may be favored instead.
