Answer:
The initial value is 1 and the base is 3.1. This is an exponential function.
Step-by-step explanation:
The function y=3.1^x is an exponential function because it has as an exponent the variable x. This is the dominant operation int he function.
Every exponential function has an initial value and base. The basic form is [tex]y = a*b^x[/tex] where a is the initial value and b is the base. It is important to remember that a can be 1.
Here the base is 3.1. At first it appears there is no initial value since no a can be seen, however if no a is present then a = 1.
