What is the opposite of exponential decay?

1 Answer

I am not sure what you meant by "opposite", but one way to think about it would it be exponential growth.

Exponential Growth can be in two directions; up and away from the asymptote (often the x-axis), or down and away from the asymptote.

Exponential Decay is towards the asymptote, whether it's from above or below the x-axis .
