Найдите область определения и область значений функции y=2√(4-|x|)-1.

\[y = 2\sqrt{4 - |x|} - 1\]

\[4 - |x| \geq 0\]

\[|x| = 4\]

\[x = \pm 4\]

\[- 4 \leq x \leq 4\]

\[D(y) = \lbrack - 4;4\rbrack.\]

\[x = \pm 4 \rightarrow y = - 1.\]

\[x = 0 \rightarrow y = 3.\]

\[E(y) = y \in \lbrack - 1;3\rbrack.\]
