I don't know how to approach this.
Here's what I've done so far.
$ x$ | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
$ y = \lfloor \sqrt x \rfloor$| 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3
$ z = x^2 $| 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
$\frac{dz}{dx} = 2n+1$| 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
This is part of my first university maths-module course work.
