Sketching a Quadratic Graph and Identifying Its Turning Point and Intercepts

Secondary 3
  1. Sketch the graph of \(y=-{{(x-1)}^{2}}+3\)
    Indicate clearly the values where the graph crosses the intercepts and coordinates of the turning point clearly.
  2. Write down the coordinates of the turning point of \(y=-{{(x-1)}^{2}}+3\).
