Answer:
The correct answer is: c. {-3, 0, 4, 11}
Step-by-step explanation:
A function consists of ordered pairs. In the ordered pairs, the first element is the input and second value is the output.
All the possible set of inputs for a function are called domain.
Given function is:
{(-3, 6), (0, 2), (4,
7), (11, 15)}
The domain set will consist of the first elements of all the ordered pairs.
The domain of this function is: {-3,0,4,11}
Hence,
The correct answer is: c. {-3, 0, 4, 11}
Sequence A is the only one with a common difference (-6).
_____
Sequence D comes close, but its first difference is 5 while the others are 6. Hence there is no common difference.
With this equation, all you have to do to solve for a is to divide both sides by 12b and <u>your answer will be 
</u>
