Answer:
We conclude that the function represents exponential growth.
Step-by-step explanation:
Given the function

As the function is of the form
and base 'b' > 1
We know that when the base 'b' of the exponential function > 1, meaning those numbers will get bigger, we call it exponential growth.
As b=8/5 is bigger than 1.
i.e. 8/5 > 1
Thus, we conclude that the function represents exponential growth.
