21 The curve with equation \(y = \mathrm{f}(x)\) has one turning point.
The coordinates of this turning point are \((-6, 9)\)

(a) Write down the coordinates of the turning point on the curve with equation \(y = \mathrm{f}(3x)\) (1)

The curve C with equation \(y = \mathrm{g}(x)\) is transformed to give the curve S with equation \(y = \mathrm{g}(x + a) + b\)

The point \((4, -5)\) on C is mapped to the point \((1, -16)\) on S

(b) Write down the value of \(a\) and the value of \(b\) (2)
