As far a domain, you only care about the denominator and radicals.
f(x) = 2 - √x is the denominator, so it can't be 0.
Also x is under a radical, so x can't be negative.
Set the denominator equal to 0 to find the excluded values.
2 - √x = 0
-√x = -2
√x = 2
x = 4, so 4 is an excluded value
The domain is all real numbers greater than or equal to 0, except 4.
[0, 4) U (4, ∞)
0 ≤ x < 4 U x > 4

Answer: The maximum numbers of rose bushes in garden is 16.
Explanation:
It is given that for every 18 mums she plants 12 tulips and for every 9 tulips there are 2 rose bushes.
Let the mums, tulips and roses are defined by M, T and R respectively.
From the given information,




Since it is given that
, we get,





From the above equation 110 mums we need 16.3 roses. So, the number mums exceeds 110 if the roses are 17.
Therefore, the maximum numbers of rose bushes in garden is 16 for which the number of mums cannot exceed 110.
