An idea. Don’t think these are the typical a level questions but just conceptual understanding of how differentiation works. For fractions remember to ensure it is proper before you limit x to anything. And if denominator grows exponentially but numerator doesn’t means something big/something very very very very big = 0+. The first derivative thing is technically asking you take 2 points and find gradient. Then for the d/dx have to recognise if there’s only one function or multiple (eg f(x)/g(x)) to apply product rule.
