Question

Which is an exponential decay function?

Answer 1

The equation is y = b(1-r)^t

It is the formula you use if the amount or total each year is decreasing. Y is the total at the end of the year, b is the start amount, r is the rate (convert all % to decimal first), and t is the number of years (that have passed since start year).

Answer 2

y increases by x 2. More Examples of Exponential Functions: Graph with 0 < b < 1. Each time x in increased by 1, y decreases to ½ its previous value. ... Any quantity that grows (or decays) by a fixed percent at regular intervals is said to possess exponential growth or exponential decay. idk fi thats what u wanted ?? but i hope it helped
