Step-by-Step Solution

To find the vertex of the parabola given by the equation y=(x+2)23 y = (x+2)^2 - 3 , we will use our understanding of the vertex form of a quadratic equation.

The vertex form of a quadratic equation is expressed as:

y=a(xh)2+k y = a(x-h)^2 + k

In this formula, the vertex of the parabola is located at the point (h,k)(h, k).

Now, let's compare the given equation y=(x+2)23 y = (x+2)^2 - 3 with the standard vertex form:

  • Notice that the expression inside the bracket is (x+2) (x+2) . This can be rewritten as (x(2)) (x - (-2)) , which highlights that h=2 h = -2 .
  • The constant term at the end is 3-3, which corresponds to k=3 k = -3 .

Therefore, the vertex of the parabola is (2,3)(-2, -3).

Checking against the provided choices, the correct answer is option 1: (2,3)(-2, -3).

Thus, we conclude that the vertex of the parabola is (2,3)(-2, -3).

Answer

(2,3) (-2,-3)
