What is the domain of this quadratic function? y = x^2 - 6x + 8 Choices: (A){x | x ≤ 3} (B){x | x ≥ 3} (C){x | x ≥ -1} (D)all real numbers

Definition of Domain: The domain of a function refers to the set of all possible input values (x-values) that the function can accept. For a quadratic function, which is a polynomial function, the domain is typically all real numbers because you can plug any real number into the function and get a real number out.Quadratic Function Domain: Since there are no restrictions on the x-values for a quadratic function like y = x^2 - 6x + 8 (no square roots or denominators that could become zero), the domain is all real numbers.

\newline

Choices:

\newline

(A)

\{x | x \leq 3\}

\newline

(B)

\{x | x \geq 3\}

\newline

(C)

\{x | x \geq -1\}

\newline

(D)all real numbers

Definition of Domain: The domain of a function refers to the set of all possible input values ( $x$ -values) that the function can accept. For a quadratic function, which is a polynomial function, the domain is typically all real numbers because you can plug any real number into the function and get a real number out.
Quadratic Function Domain: Since there are no restrictions on the $x$ -values for a quadratic function like $y = x^2 - 6x + 8$ (no square roots or denominators that could become zero), the domain is all real numbers.
