Question

The base of an exponential function can only be a positive number true or false?

Answer 1

The given statement:

The base of an exponential function can only be a positive number is a TRUE statement.

Explanation:

In mathematics, an exponential function is a function of the form

`f(x)=ab^x`

where b is a positive real number, and in which the argument x occurs as an exponent and a is a constant which can be both positive as well as negative.

The term 'b' is called base of the exponential function.

Hence, the base of an exponential function can only be a positive number.

Answer 2

The base of an exponential function can only be a positive number: it is TRUE
Proof
for all value of x, e^x always positive
