We can't see the whole question :/
The domain of the function is possible values of independant varaible such that function is defined or have real values.
So the expression

is not defined for x = -6 and for x = 1, as expression becomes undefined for this values of x (Denominator becomes 0).
So answer is,

Option B is correct.
Answer:
The original duration of the tour is 18 days.
Step-by-step explanation:
Let
the number of days spent be T
Daily expenses be D
Initially ,
total tour expenses was 360

-------------(1)
If he extends his tour for 4 days, he has to cut down his daily expenses by dollar 3
---------------(2)
Expanding the eqaution(2)
DT-3D + 4T -12 = 360
Substituting the value of D







Solving the quadratic equation we get
T = 18 and T = -15
T is the number of gays and it cannot be negative , hence T is 18
Substituting in equation (1) we get

D = 20
Answer:
45 grams
Step-by-step explanation:
1st order: 27 people
15 people:
100 g
Ginger: 20 g
Turmeric: 25 g
Coriander: 35 g
Cumin Seeds: 20 g
20+25+35+20=60+40=100
For 1 person:
Ginger: 1 1/3 g
Turmeric: 1 2/3 g
Coriander: 2 1/3 g
Cumin Seeds: 1 1/3 g
Multiply all that by 27
For 27 people:
Ginger: 36 g
Turmeric: 45 g
Coriander: 63 g
Cumin Seeds: 36 g
45 g for Turmeric
