Well, in Politics in particular, examiners are looking for evidence that you are a student that understands and can talk confidently about complex political phenomena. Do this by making it clear that you ...

Differentiate the curve to get the gradient function: f'(x)= 2x + 5. Solve for x when f'(x) = 0 --> 2x + 5 = 0, 2x = -5, x = -5/2 Substitute into the original equation to find y: (-2.5)^2 + 5 * -2.5 + ...
