Which statements are true about decay functions

Well maybe give me some options. But the statements that are true about decay functions are exponential decay are; the domain is all real numbers, the base must be less than 1 and greater than 0 and the function has a constant multiplicative rate of change. The answers are letters A, D and E. An example is when there are 70000 bacteria present in a culture and reduced by half every four hours, the number of bacteria will decrease. The bacteria will experience an exponential decay because it decreases its number at a constant decay.

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
