Step-by-step explanation:
The domain of f(x) is all values of x for which f(x) is defined.
For f(x) to be defined, the expression under the radical must be non-negative.
Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).
Ax^2 + bx + c
a = 1
b = -4
c = -5
x^2 -4x-5
-5x1 = -5
-5+1 = -4
(factors of c that also add up to b)
ANSWER: (x-5) (x+1)
Answer:

Step-by-step explanation:
The function is
where x is the number of bottles of soda.
The domain means the set of "allowed" x values.
Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:

This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>
