Will give brainliest if right!! (if both right is okay, ill brainliest the first person)

Is this a polynomial function? i need to know asap

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.

What is the best way to answer questions with a x expression in the question. for example 3x + 10x=?
