Find the vertex of the parabola

y=(x+14)214 y=(x+14)^2-14

Step-by-step solution

To find the vertex of the parabola expressed by the equation y=(x+14)214 y = (x+14)^2 - 14 , recognize that this is given in the vertex form of a quadratic equation:

  • The general vertex form of a quadratic equation is y=a(xh)2+k y = a(x-h)^2 + k , where (h,k) (h, k) represents the vertex of the parabola.

In the given equation:

  • The x x term inside the parentheses is x+14 x+14 , which can be rewritten as x(14) x - (-14) . This implies h=14 h = -14 .
  • The constant term outside the parentheses is 14-14, which is the k k value indicating the vertical shift. Hence, k=14 k = -14 .


Therefore, the vertex of the parabola is determined by (h,k)=(14,14) (h, k) = (-14, -14) .

The solution to the problem is (14,14) (-14, -14) .
