The vertex of the parabola represented by f(x)=x^2-2x+6 has coordinates (1,5). find the coordinates of the vertex of the parabola defined by g(x)=f(x+3). explain how you arrived at your answer

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
