QuestionFind the domain of the piecewise function $f(x)=\begin{cases} 2+x & \text{if } x<0 \\ x^{2} & \text{if } x \geq 0 \end{cases}$.

Studdy Solution
However, the union of these two sets is all real numbers, which can be represented as $(-\infty, +\infty)$.
The domain of the function is all real numbers.
