Question

Identify the domain of the equation y = x2 − 6x + 1.

x ≤ 3

x ≥ −8

x ≥ −2

All real numbers

Answer 1

The correct option is 4.

Explanation:

Domain is the set of all possible inputs for which the given function is defined.

The given function is

`y=x^2-6x+1`

It is a second degree polynomial. These type of polynomial are defined for all real values of x. So, the domain of the given function is all real numbers.

`Domian=\{x:x\in R\}`

`Domian=R`

Therefore the correct option is 4.

Answer 2

The domain is all real numbers.
