It goes with the word above it, and means find the lim(it) as h tends to zero.
3. I think it means, find this for when h approaches 0

Thanks. All the 'h's cancel out right? Simple enough
5. bassically it's your iiA) value over h, simplify it and find what happens when h = 0

I think it represents the gradiant because dy/dx = 4x^3

It represents the derivative evaluated at the point x because it's the definition of the derivative evaluated at the point x.
