D Question 21 3 pts Using the binomial theorem, expand the following: (x - 3)3 O x3 - 27 Ox - 9x' + 27x - 27 O 2 + 27 O x3 + 3x' + 3x + 1 D Question 22 3 pts Which of these rational functions will have a hole at -2 and a vertical asymptote at a = 3? (x-2)3 (r+3)(x-2) Of(x) = 2+2 Of (a) = - (2+2) 2 (r -3) (x+2) Of(x) = (*-4)(x+2) (an + 2 )2
