Step-by-step explanation:

The function is given below as


f(x)=3((5)/(4))^x

Concept:

An exponential function is a function in which the variable is an exponent. Exponential functions are written in the form f(x)=ab^x f ( x ) = a. b^ x . Initial Value: The initial value of an exponential function is the result of substituting x=0 into the function.

Hence,

by putting x=0, we will have the initial value be


\begin{gathered} f(x)=3((5)/(4))^(x) \\ f(0)=3((5)/(4))^0 \\ f(0)=3 \end{gathered}

Hence,

The initial value is


3

Part B:

The genral equation of an exponential equation is given below as


\begin{gathered} y=ab^x \\ a=constant \\ b=base \end{gathered}

By comparing coefficnets,

The base for this function is


(5)/(4)

Part C:

The domain of the function is given below as


\begin{bmatrix}\mathrm{Solution:}\:&amp;\:-\infty \:<strong>Part D:</strong><p><strong>The range of the function is given below as</strong></p>[tex]\begin{bmatrix}\mathrm{Solution:}\:&amp;\:f\left(x\right)>0\:\\ \:\mathrm{Interval\:Notation:}&amp;\:\left(0,\:\infty \:\right)\end{bmatrix}
