We know that According to Algebra of Real Functions :
If f and g are two real functions which are defined under the same domain then 

Now we need find the Domain of this Function :
The Condition for Square Root to be defined is any Expression under it should be Greater than or Equal to Zero.
When Function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)
According to Above Conditions Described above, The Given Function is Definable only when the Expression which is under the Square Root is Greater than Zero and x ≠ 0
⇒ 3x - 9 > 0
⇒ 3x > 9
⇒ x > 3
⇒ The Domain of the Given Function is (3 , ∞)
1st Option is the Answer
Answer:
B
Step-by-step explanation:
The answer is ''B'' cause it is the only true statement
Ok so what you have to do is multiply all the numbers ! Hope this helps so the answer is 127 !
The number is 74.
- It’s a two digit even number.
- 7 + 4 = 11
- 74 reversed is 47. 74 - 47 = 27.
