Question

Determine the domain of the function in the correct set notation.

f(x) = 2x+6


O x


O x ER, x + 3


O x


O x € R, x*-2

Answer 1

{x|x
`\in R`}

Explanation:

We are given that a function

`f(x)=2x+6`

We have to find the domain of the function in the correct set notation.

The given function is linear polynomial .

The linear polynomial is defined for all real values of x.

Therefore, the given function is defined for values of x.

Domain of f is given by

{x|x
`\in R`}

Hence, the domain of the function in the correct set notation is given by

{x|x
`\in R`}
