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.

The answer is a or b
