Question: Given that \(f\left( 2 \right)=3\), \(f'\left( 2 \right)=8\), \(g\left( 3 \right)=2\) and \(g'\left( 3 \right)=4\)

(a) Find \(h'\left( 2 \right)\), where \(h\left( x \right)=\left( {{x}^{2}}+1 \right)f\left( x \right)\)

(b) Find \(h'\left( 3 \right)\) where \(h\left( x \right)=\frac{g\left( x \right)}{7-3x}\)
