Which function's domain consists of only real numbers greater than 3?
a. rx) = 3x
b. f(x)=vi
c. rx) = 3x + 4
d. f(x) = 1 1 - 3

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
