PLEASE HELP!!!!!!
Determine if the function f is an exponential function. If so, identify the base. If not, why not? f(x)= (-1/4)^x-3.141

A) This is not an exponential function because the base must be a positive value.


B) This is a polynomial.


C) The base is −4−1.


D) The base is 3.141.

Respuesta :

The function f has a an exponent which is the variable ( the letter x) therefore it is an exponential function.

The base is the number being raised by the exponent ( -1/4)
