Answer:
B
Step-by-step explanation:
We can figure out the initial value and base of an exponential function if the function is written in the form [tex]y=a*b^x[/tex] where
a is the initial value, and
b is the base
Note: a ≠ 0 and b ≠ 1
Our equation given can be written in this form by writing it like [tex]y=5^x\\y=1*5^x[/tex]
Thus, this is an exponential function. The initial value is 1 and the base is 5.
The correct answer is B
