Which statement is true about the discontinuities of the function f(x)?

f(x)= x^2-4/x^3-x^2-2x

A. There is a hole at x = 2.

B. There are asymptotes at x = 0 and x = –1.

C. There are asymptotes at x = 0 and x = –1 and a hole at (2,2/3).

D. There are holes at x = 0 and x = –1 and an asymptote at x = 2.

ANSWER IS C. There are asymptotes at x = 0 and x = –1 and a hole at (2,2/3).
