ANSWER:
Yes, the function represents exponential growth
STEP-BY-STEP EXPLANATION:
Exponential growth models apply to any situation where growth is proportional to the current size of the interest amount.
Exponential is understood as the saying of growth or development, of a rhythm, cadence or proportion that increases or increases each time rapidly and noticeably. It has the following form:
[tex]y=C\cdot(1+r)^t[/tex]In this case we have the following function
[tex]f(x)=8\cdot2^x[/tex]Since the variant value (x) is in the exponent we can conclude that if it is a function with exponential growth
