Find f if f′(x)=2x−3/x^4, x> 0 and f(1)=2.

Which ahows the graph of the solution set of 6x+4y< 12

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

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.
