Question

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

x ≤ 3

x ≥ −8

x ≥ −2

All real numbers

Answer 1

The domain is all real numbers.

Answer 2

Answer:

The correct option is 4.

Step-by-step 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.
