<u>Answer</u>:
1296 windows are present in the building
<u>Explanation:</u>
Given the office building is 48 floors high
Half of floors have 18 windows each
Then , half of floors = = 24 floors
Total windows on half of the floors, that is 24 floors
=
= 432 windows
Also, half of the floors have 36 windows each
Total windows on rest half floors (24 floors)
=
= 864 windows
Total windows = 432 + 864 = 1296 windows
Therefore, 1296 windows are present in the building

It looks like you have the domain confused for the range! You can think of the domain as the set of all "inputs" for a function (all of the x values which are allowed). In the given function, we have no explicit restrictions on the domain, and no situations like division by 0 or taking the square root of a negative number that would otherwise put limits on it, so our domain would simply be the set of all real numbers, R. Inequality notation doesn't really use ∞, so you could just put an R to represent the set. In set notation, we'd write
and in interval notation,
The <em>range</em>, on the other hand, is the set of all possible <em>outputs</em> of a function - here, it's the set of all values f(x) can be. In the case of quadratic equations (equations with an x² term), there will always be some minimum or maximum value limiting the range. Here, we see on the graph that the maximum value for f(x) is 3. The range of the function then includes all values less than or equal to 3. As in inequality, we can say that
,
in set notation:
(this just means "f(x) is a real number less than or equal to 3")
and in interval notation:
