15. Explain the key features of the exponential function y = a · b*, including the asymptote, key points on the graph, domain, and range.

In which form is the following function written? y = - 2(x – 3)(x + 5)

Prove that quadrilateral is a rhombus.

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.
