The table shows a pattern of exponents. what is the pattern as the exponents decrease?

What is the vertical asymptotes of the function f(x)=x-2/x*2-3x-4

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
