Question

This problem involves a limit and the greatest integer function. My current guess is B. 1/3.5. I plugged 3.5 in for x. My numerator became 1.5, but I rounded down to 1 because it is the greatest integer function and ended up with 2/7 or 1/3.5

Answer 1

Yes your answer is correct. Nice job.

You should get 1 in the numerator when you plug in x = 3.5 and evaluate/simplify
In the denominator is simply 3.5

So you'll have 1/3.5 = 1/(7/2) = 2/7 as the final answer
