Multiple Choice

Decide if the function is an exponential function. If it is, state the initial value and the base.
- $$y = 9 ^ { 3 }$$

A) Exponential Function; base $= 9$ ; initial value $= 0$
B) Exponential Function; base $= 3$ ; initial value $= 0$
C) Not an exponential function
D) Exponential Function; base $= 9$ ; initial value $= 1$
