Solution
- We have been given a table of values for a quadratic function and we are asked to find the coordinates of its vertex.
- We can simply plot the graph of the quadratic function and observe its vertex coordinates.
- The graphed function is given below
- The vertex of a quadratic equation is the coordinate of the turning point of the graph.
- From the above, we can see that the vertex coordinates must be (2, -9) because that is the point where the graph turns from moving downwards to moving upwards.
Final Answer
The coordinate of the vertex is (2, - 9)
