\end{figure} Figure 1 shows a sketch of the curve \(C\) with equation \(y = \mathrm { f } ( x )\) The curve \(C\) passes through the origin and through \(( 6,0 )\) The curve \(C\) has a minimum at the point \(( 3 , - 1 )\) On separate diagrams, sketch the curve with equation
  1. \(y = \mathrm { f } ( 2 x )\)
  2. \(y = \mathrm { f } ( x + p )\), where \(p\) is a constant and \(0 < p < 3\) On each diagram show the coordinates of any points where the curve intersects the \(x\)-axis and of any minimum or maximum points.
    a) \(( 6,0 ) \rightarrow ( 3,0 )\) $$( 3 , - 1 ) - 1 > ( 1.5 , - 1 )$$
