9. In an exponential function Q = abt, exponential decay happens when the base, b, is 10. For the given statement, identify the growth factor, b, and its corresponding growth rate, r, and the decay rate. Statement: "A quantity..." a) Goes down by 3/5 b) Shrinks by 1/5 c) Has 64% decay d) Drops by 90% e) Decreases in value by 3% Growth factor (b) Growth rate (r) (as a percent) Decay rate (as a percent)
