Answer:
Option: d is the correct answer.
d. 15
Step-by-step explanation:
We are given a exponential function as:
[tex]f(x)=\dfrac{1}{5}(15^x)[/tex]
We know that in general a exponential function is represented by:
[tex]f(x)=ab^x[/tex]
where a is the initial amount and b represents a growth factor if it is strictly greater than 1 and a decay factor if 0<b<1
Hence, the value of the growth factor of the function is:
d. 15
