MCQ
વિધેય $f(x)=\sqrt{3-x}+\sqrt{2+x}$ નો વિસ્તાર $.........$ છે.
- ✓$[\sqrt{5}, \sqrt{10}]$
- B$[2 \sqrt{2}, \sqrt{11}]$
- C$[\sqrt{5}, \sqrt{13}]$
- D$[\sqrt{2}, \sqrt{7}]$
$=5+2 \sqrt{6+x-x^2}$
$y^2=5+2 \sqrt{\frac{25}{4}-\left(x-\frac{1}{2}\right)^2}$
$y_{\max }=\sqrt{5+5}=\sqrt{10}$
$y_{\min }=\sqrt{5}$
