Question

फलन y = f(x) = √x+2 का प्रांत का परिसर ज्ञात कीजिए

Answer 1

हल-

.

फलन f परिभाषित है यदि x + 2 > = 0

x >= -2

अर्थात .......

प्रांत = [-2,∞)

प्रत्येक x >= 2, √x+2 ε[0,∞)

परिसर ⊂ [0,∞)

जबकि l ε [0,∞]

$\f( /lamda {}^{2} - 2) = \sqrt{( /lamda {}^{2} - 2) + 2 = /lamda}$

अतः

परिसर= [0,∞)

Answer 2

HEY MATE HERE IS YOUR ANSWER

. Falan f paribhashit hai yadi x +2 > = 0

X = - 2


Means that,

Prat = (-2, °°)

But,

X =2 /~x +2, 3{0,°°}

Parisar : U [0,°°]

Therefore,

Answer :- [0, °°]
