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.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
