It is known that the opening direction and size of the parabola Y1 = a (X-H) 178; + K and y2 = (X-2) 178; - 7 are the same, and the lowest point is the same It is known that the opening direction and size of the parabola Y1 = a (X-H) & # 178; + K and y2 = (X-2) & # 178; - 7 are the same, and the coordinates of the lowest point are (- 1, - 2). Find the functional relationship of the parabola Y1, and point out whether the parabola Y1 can be obtained by Y2 translation, and if so, how to translate it
Y2 = (X-2) & # - 7 vertex (2, - 7)
A = 1, H = - 1, k = - 2
Parabola Y1 = (x + 1) & # - 2
The parabola Y1 can be obtained by Y2 translation. Y2 can be translated three units to the left and then five units to the up
