If f(x) = ab^x where a > 0, b > 0, and b is not equal to 1, then b is called the _______________ of the exponential function.

Any help is greatly appreciated!! :)

Here is a formal definition of the exponential function, which you probably will find in your textbook:

The exponential function with base a is defined for all real numbers x by
f(x) = ax where a>0 and a≠1.

Can you take it from here?
