An exponential growth function represents a quantity that has a constant halving time. true or false?

An exponential decay function represents a quantity that has a constant halving time. But here is the question about an exponential growth function.A = Ao * k^t1/2 x = x * k^t1/2 = k^tln(1/2) = t * ln kt = ln(1/2) / ln k   - the halving time for any exponential decay function. False.

Are there any statements?
