Answer:
a.0 ≤ x ≤ 30, where x is a whole number
Step-by-step explanation:
a vacation rental company uses the function v(x)=250x+75
x is the number of nights
maximum number of nights = 30
The number of nights cannot be negative
The domain is the set of x values for which the function is defined
we ignore the negative value for x in the domain because number of nights cannot be negative
so x starts at 0 and maximum is 30
number of nights should be a whole number
0 ≤ x ≤ 30, where x is a whole number
