Question

What are growth and decay formulas

Answer 1

Answer:

Exponential Growth: y = a(1 + r)x

Exponential Decay: y = a(1 - r)x

Explanation:

Remember that the original exponential formula was y = abx.

You will notice that in these new growth and decay functions,

the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).

The growth "rate" (r) is determined as b = 1 + r.

The decay "rate" (r) is determined as b = 1 - r
