We would like to find the vertex and the axis of symmetry of the graph of the function
First, we note that the function is on the form where and , so we can use the characteristics of the function to find the vertex and the axis of symmetry of the graph of .
Since we know that in the function the vertex is , so the vertex of the graph of is .
Also in the function we know that the axis of symmetry is , so the axis of symmetry of the graph of is .
