Does the relation y=x^2-1 defines y as a function of x

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

Which of the following is the result of expanding

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.
