It's really not a matter of interpretation. Geometric and exponential growth are well defined mathematical concepts.
Geometric functions can have exponents. This does not imply the function is exponential. These are very different things.

- AnimalMuppet 2y agoThe page you cite gives the formula for exponential growth as: {\displaystyle x_{t}=x_{0}(1+r)^{t}} Um, right, let me translate that into something that can display here: x(t) = x(0) * (1+r)^t Well, if you look at the formula I gave for compound interest: x(t) is the value at time t, x(0) is the value at time 0, namely $1000, (1+r) is 1.05, and t = n, the number of years. So, from your own cited article, how is that not exponential? Or were you agreeing with me, and disagreeing with glitchc?
- glitchc 2y agoMy quibble was about geometrics vs exponential, but beyond the mathematical distinction of discreteness, they are equivalent, so I stand corrected on that front.
