Beyond the Answer
The vertex is at the point \((-2, -3)\), which is derived from the standard form of the function. In this format, the values of \(h\) and \(k\) in \((x-h)^2 + k\) indicate the x and y coordinates of the vertex, respectively. Here, \(h = -2\) and \(k = -3\) gives us the vertex as \((-2, -3)\). To graph this function effectively, you can use the vertex as a starting point. Since the equation opens upward (the coefficient of \(x^2\) is positive), you can plot points on either side of the vertex. This helps in sketching a delightful U-shaped parabola that will curve up through the vertex, producing a beautiful visual of quadratic nature!
