    1. Express \(x ^ { 2 } - 6 x + 11\) in the form \(( x - p ) ^ { 2 } + q\).
    2. Use the result from part (a)(i) to show that the equation \(x ^ { 2 } - 6 x + 11 = 0\) has no real solutions.
  1. A curve has equation \(y = x ^ { 2 } - 6 x + 11\).
    1. Find the coordinates of the vertex of the curve.
    2. Sketch the curve, indicating the value of \(y\) where the curve crosses the \(y\)-axis.
    3. Describe the geometrical transformation that maps the curve with equation \(y = x ^ { 2 } - 6 x + 11\) onto the curve with equation \(y = x ^ { 2 }\).
