Answer:
Option D
Step-by-step explanation:
Consider the four options being substituted
[tex]A) 2(1^x) = 2[/tex] will be option I which is a constant function
B) [tex]f(x) = \frac{1}{2}(\frac{1}{3} )^x[/tex]
But here since a <1 we find this is a decay function
C) Here since a=1 this is a constant funciton.
D) [tex]. P=2; a=3[/tex]
[tex]f(x) = 2(3)^X[/tex]
As x increases by 1, we get f(x) increases by 3 times
Hence this is exponential growth
