оЗа. [3 marks] y=\frac{x^{2}+5}{x-2} . \text { Use the Quotient Rule to find } \frac{d y}{d x} \text {. } (1)Use the Product Rule to differentiate the function y = (4x2)(2x + 4). \text { (ii) Hence, evaluate } \frac{d y}{d x} \text { when } x=-1 \text {. } Find the area bounded by the curve y = 3x2 + 4x, the x-axis, the line x = 1and the line x = 3.
