that is where the two graphs intersect
(2/3a • 9a) + (2/3 • 6) = 23.8
a = 2.1259 or 287/135

Answer: C. {x ∈ N | x > 2}
Step-by-step explanation:
Domain is the set of all possible input values or x- values in a function for which it is defined.
Given: A group of 6 students are surveying their classmates.
Assume that each students surveyed equal number of classmates.
So total number of complete surveys = 6 x (number of classmates surveyed by each)
Also s(x)=6x, here x = number of classmates surveyed by each student.
Since, each student surveys more than 2 of their classmates, so x >2.
So required domain= {x ∈ N | x > 2} , because number of students is always a natural number.
Therefore, correct option is C. {x ∈ N | x > 2}
