Question

an exponential decay function represents a quantity that has a constant halving time. a. true b. false

Explanation:

An exponential decay function is of the form \( y = a(1 - r)^t \) (or \( y = ae^{-kt} \) for continuous decay). The halving time (time to reduce to half the original quantity) is constant. For example, if a substance decays with half - life \( T_{1/2}\), after each \( T_{1/2}\) period, the quantity is halved, regardless of the initial amount. So an exponential decay function represents a quantity with a constant halving time.

Answer:

A. True
