Найдите область определения и область значений функции y=3√(1-|x|)+1.

\[y = 3\sqrt{1 - |x|} + 1\]

\[1 - |x| \geq 0\]

\[|x| = 1\]

\[x = \pm 1.\]

\[- 1 \leq x \leq 1.\]

\[D(y) = x \in \lbrack - 1;1\rbrack.\]

\[x = \pm 1 \rightarrow y = 1.\]

\[x = 0 \rightarrow y = 4.\]

\[E(y) = y \in \lbrack 1;4\rbrack.\]
