Can someone please help ?

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x

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.

Y=(x+3)(x-4)(x+1)^2 sulutions? multiplicity?
