Q. If the equation y=x2+9 is graphed in the xy-plane, what are the coordinates of the vertex of the graph?Choose 1 answer:(A) (−3,0)(B) (0,3)(C) (0,9)(D) (9,0)
Identify Form: Identify the form of the given quadratic equation.The given equation is y=x2+9, which is already in the form y=a(x−h)2+k, where a=1, h=0, and k=9.
Determine Vertex: Determine the vertex of the parabola.For a parabola in the form y=a(x−h)2+k, the vertex is at the point (h,k). From the equation y=x2+9, we can see that h=0 and k=9.
Write Coordinates: Write down the coordinates of the vertex.The coordinates of the vertex are (0,9).
