Answer:

Slant asymptote { #y=x+7.
Vertical asymptote : x = 3.

Explanation:

graph{((x^2+4x+4)/(x-3)-y)(y-x-7.9)(x-2+.01y)=0 [-45, 45, -20, 25]}

The graph is a hyperbola

#(y-x-7)(x-3)=15# having asymptotes given by

#(y-x-7)(x-3)=0#, with a hole at (2, -16)

#h =((x-2)/(x-2))((x^2+4x+4)/(x-3))#.

Sans the hole at x = 2,

#h=(x^2+4x+4)/(x-3)#

#=x+7+25/(x-3)#.

So, #y = quotient=x+7# gives the slant asymptote and

#x-3 = 0# gives the vertical asymptote.
