An exponential function is written as f(x) = a bx, where the coefficient a is a constant, the base b is but not equal to 1, and the exponent x is any number. a. positive
b. real
c. an integer
d. negative

A.Positive

Step-by-step explanation:

We are given that an exponential function

Where a=Constant coefficient

x=Any real number

We have to fill the correct word in blank space.

We know that

Exponential function : It is that function in which independent variable is exponent.

It is represented by

Where a>0,

By definition of exponential function

Base b is positive but not equal to 1.
