Question

question suppose that a linear equation relating y and x is given by y = 2x + 3, where x is an independent variable and y is a dependent variable. which of the following is a correct function - notation representation of y? select the correct answer below: o f(x)=2y + 3. o f(y)=2y + 3. o f(x)=2x + 3. o f(y)=2x + 3.

Explanation:

Step1: Recall function - notation concept

In function - notation, if $y$ is a function of $x$, we write $y = f(x)$.

Step2: Identify the given equation

The given linear equation is $y=2x + 3$.

Step3: Write in function - notation

Since $y$ is a function of $x$, we can rewrite it as $f(x)=2x + 3$. So the correct function - notation representation of $y$ is $f(x)=2x + 3$.

Answer:

C. $f(x)=2x + 3$
