Answer:

D.

x = all real numbers

Explanation:

The domain of a function is the set of input or argument values for which the function is real and defined.

The function has no undefined points nor domain constraints. Therefore, the domain is


-\infty \:<x<\infty \:


\mathrm{Domain\:of\:}\:2\left|x-1\right|+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&amp;\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&amp;\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}\\
