d. (0, 4)

Consider the graph of the exponential function y=3(2)×

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.

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?
