Find vertex:

Use the value you found for the axis of symmetry as the  x - coordinate of the vertex.

To find the y-coordinate, substitute that value for x in the original equation.

     (Substitute )

         (Evaluate powers: )

               (Apply multiplicitive identity property: )

                               (Add: )

The vertex is at (1,2).

Find y-intercept:

The graph is observed that,

The y-intercept is the point where the graph intersects the y-axis. It is located at (0,1), so the y-intercept is 1.

The equation of the vertex is (1,2), the axis of symmetry is  x = 1 and y-intercept is 1.
