Answer:
Explanation:
a) To represent this scenario with a function, you can define a function f(x) where x represents the number of sips Anna takes. Each sip is 10 ounces, and the water bottle holds 120 ounces. So, the function would be:
f(x) = 120 - 10x
b) To find out how many sips Anna can take before she needs to refill, you can set the function equal to 0 and solve for x:
120 - 10x = 0
10x = 120
x = 12
Anna can take 12 sips before she needs to refill the water bottle.
c) Here's a graph representing the situation:

d) The domain of the function represents the values that x can take. In this case, x represents the number of sips, so it must be a whole number. Therefore, the domain in set notation is:
Domain: x is a whole number, x ≥ 0
