Find the domain.
-$$f ( x ) = x ^ { 3 } + 4$$
A) $\{ x \mid x$ is a real number and $x \neq - 4 \}$
B) All real numbers
C) $\{ x \mid x$ is a real number and $x \neq 4 \}$
D) $\{ x \mid x$ is a real number and $x \neq \sqrt [ 3 ] { 4 } \}$

Question

Quizplus · Accepted Answer

The function $f(x) = x^3 + 4$ is a polynomial, and polynomials are defined for all real numbers, meaning there are no restrictions on the domain.

Find the Domain f(x)=x3+4f ( x ) = x ^ { 3 } + 4f(x)=x3+4

Find the Domain $f ( x ) = x ^ { 3 } + 4$
