Definice oboru funkce
Urči definiční obor funkce:
\( h: y=\sqrt{x+x^{2}-2 x^{3}} \)
\( D(h)=\left(-\infty ;-\frac{1}{2}\right) \cup\langle 0 ; 1\rangle \)
\( D(h)=\left(-\infty ;0\right) \cup\langle 1 ; 2\rangle \)
\( D(h)=\left(-1 ;0\right) \cup\langle 0 ; 1\rangle \)
\( D(h)=\left(-\infty ;-1\right) \cup\langle 0 ; \frac{1}{2}\rangle \)
