Answer:
D
Step-by-step explanation:
Exponential equation takes the form [tex]y=a*b^x[/tex] where
- a is the initial value ( a ≠ 0), and
- b is the base ( b ≠ 1)
The equation given in the problem can be written as [tex]y=-4.8*4^x[/tex], so it is an exponential equation, where a = -4.8 and b = 4.
Thus we can say that the initial value = -4.8 and the base is 4
The correct answer is D
