Answer:
   C.  {-1, 5, 8}
Step-by-step explanation:
Use each of the domain values in the function to see what the corresponding range value is. 
   f(-1) = 5 -3(-1) = 8
   f(0) = 5 -3(0) = 5
   f(2) = 5 -3(2) = -1
The range is the set of numbers {-1, 5, 8}.

<em>Additional comment</em>
The values in a set are generally listed lowest to highest. The coefficient of x in the equation for f(x) is negative, meaning the lowest range value will correspond to the highest domain value. If you start by finding f(2) = -1, you immediately eliminate all answer choices except B and C. 
Those choices differ only in the middle value, so you can tell which is correct by evaluating f(x) for the middle domain value: f(0) = 5. Only one answer choice has both -1 and 5 in the set.
(There are two answers here: how you work the problem, and how you game a multiple choice question.)
