Q. Find the coordinates of the vertex of the following parabola using graphing technology. Write your answer as an (x,y) point.y=x2−6Answer:
Identify Vertex: The vertex form of a parabola is given by y=a(x−h)2+k, where (h,k) is the vertex of the parabola. To find the vertex of the parabola y=x2−6, we need to identify the values of h and k in this equation.
Determine Coefficients: In the given equation y=x2−6, the coefficient a is 1 (since there is no coefficient written, it is understood to be 1), and there is no (x−h) term, which means h=0. The constant term is −6, which means k=−6. Therefore, the vertex of the parabola is at the point (h,k)=(0,−6).
Conclude Vertex: Since we have identified the vertex without needing to complete the square or use any graphing technology, we can conclude that the vertex of the parabola y=x2−6 is at the point (0,−6).
