Also I need help with these questions as wellD) which of these functions has a "hole"a)r(x)b)s(x)c)t(x)d)u(x)e)w(x)E) what are the asymptotes of the function r(x)

Consider the following rational functions. 2x - 1 s(x) = _x + 27 w ( x ) = x+ 6x2 + 9x (x) = (( x ) = x - 9x u ( x ) = * +x - 12 x + 3 2-x- 2 X 2+4 x + 2 x2 - 49 (a) Which of these rational functions has a horizontal asymptote? (Select all that apply.) Or(x) s( x) (( x ) Du(x ) (b) Which of these functions has a slant asymptote? (Select all that apply.) Or(x) s(x ) Of ( x ) Du( x ) w( x ) (c) Which of these functions has no vertical asymptote? (Select all that apply.) Or( x ) O s (x) Ot ( x ) Du ( x ) Ow ( x )
