(Sorry, I'm unsure how to fix the formatting, plus I'm new to this. The -6 and such on the second line should be below the 5 and following of the first line, and the 3 and such on the last line should be below the 3 and following on the first line, leaving a space between the 3 on the first and third line.)
So the answer is: A. 3x^3 - x^2 + 3x - 6 + 7/(x+2)
The answer would be C because 2/3 as a decimal is 0.6666 and it goes on forever. D is at 0.75 which is too big and a and b are less than 0.5, so C is the correct answer.
