Which statement is true about the discontinuities of the function f(x)? f (x) = StartFraction x squared minus 4 Over x cubed minus x squared minus 2 x EndFraction There is a hole at x = 2. There are asymptotes at x = 0 and x = –1. There are asymptotes at x = 0 and x = –1 and a hole at (2, two-thirds). There are holes at x = 0 and x = –1 and an asymptote at x = 2.

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's. 

Bbecause i need points
