Question

1/2 (y+4)=(x-7)^2 in vertex form

Answer 1

y + 4 = 2(x - 7)^2

Explanation:

Multiply both sides by 2 (to eliminate the fraction 1/2):

1/2 (y+4)=(x-7)^2 => y + 4 = 2(x - 7)^2

From this we can immediately read off the coordinates of the vertex; they are (7, -4). This vertical parabola opens upward.
