Question

!!!50 POINTS!!! Help Please 2. Which functions are exponential decay functions? Choose exactly two answers that are correct. A. f(x)=0.9^x B. g(x)=(6/5)^x C. h(x)=1.25^x D. j(x)=(4/5)^x

Answer 1

A characteristics of an exponential decay function is it has a constant term that is lesser than 1, this is because when you raise it a number that is lesser than 1 to higher values the result will be lesser and lesser, that is why it is called decay function. so the decay functions are a. f(x)=0.9^x and d. j(x)=(4/5)^x
