The function that represents exponential decay is f(x) = 1(2)ˣ.
What is exponential decay?
Exponential decay describes the process of reducing an amount at a consistence rate.
The general exponential decay formula is given as;
[tex]y = ab^x[/tex]
From the given options, we can conclude that the option that corresponds to the above general equation is option A.
[tex]y = ab^x\\\\f(x) = 1(2)^x\\\\y = f(x)\\\\a = 1\\\\b = 2\\\\[/tex]
