f is a function that relates the price of a product to the revenue it will generate. if a price of $5 corresponds to $8,000 in revenue, which of the following correctly shows this relation using function notation?
select the correct answer below:
$f(x)=8,000x + 5$
$f(x)=5x + 8,000$
$f(8,000)=5$
$f(5)=8,000$

Explanation:

Step1: Understand function - notation concept

In function notation $F(x)$, $x$ is the input and $F(x)$ is the output.

Step2: Identify input and output values

The price is the input and the revenue is the output. Given price $x = 5$ and revenue $F(x)=8000$.

Step3: Write in function - notation

We write it as $F(5)=8000$.

Answer:

D. $F(5)=8,000$
