For what domain is the function f(x)=2^x - 4 positive

Domain:    (-∞,∞),{x|x∈ℝ}

Message me if you need the range too. Hope this helped.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
