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.)

Answer: The correct answer is option A: 6
Step-by-step explanation: We shall start by splitting the word problem into bits to ease our calculations.
We start with “the quotient of a and 6...” and that can be expressed as
a/6 where a equals 186, this becomes
186/6 and this equals 31.
Note that quotient means the result derived from dividing two numbers/values.
Next, “The difference of ... and b squared”
The missing part of this statement has been calculated as 31, so this can now be written as “The difference of 31 and b squared” where b equals 5 and b squared now equals 25. Hence what we have is the difference of 31 and 25
That is, 31 - 25 and that equals 6.
Therefore, the expression can now be written out as;
(a/6) - b^2
When a equals 186 and b equals 5, the answer is 6
Answer: Choice A) 
Work Shown:
Use the distance formula
Points are (x1,y1) = (-4,3) and (x2,y2) = (-7,-2)
d = distance between the two points
