A) $\{ x \mid x$ is a real number and $x \neq - 1 \}$
B) $\{ x \mid x$ is a real number and $x \neq - 0.33333333 \}$
C) $\{ x \mid x$ is a real number and $x \neq - 3 \}$
D) All real numbers

The function $f(x) = 7x + 3$ is a linear function, which means its domain is all real numbers because there are no restrictions on the value of $x$. Linear functions do not have denominators or square roots that could restrict the domain.
