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:

Answer:
h ≅ 16.29 cm

Step-by-step explanation:
From the conical funnel;
Let the adjacent line at the base of the cone be radius (r) and the opposite ( vertical length) be the height (h)
Then;



∴


The volume (V) of the cone is expressed as:





Given that:

Then:




∴

c = 0
So;


t = 30

h = 16.2865
h ≅ 16.29 cm
Thus;
from

Hello there!
The correct answer is option A, because:
4(t - 6)
Use the distributive property
(4)(t) + (4)(-6)
So yeah, this is how the distributive property works.
Option A is the only option that works with the distributive property.
Let me know if you have questions about the answer. As always, it is my pleasure to help students like you!
