It didn't make sense because, if you sub x into the function, its y value would be x³

for this equation when we had to differentiate D (distance) squared am I misunderstanding something about what people are doing because
when differentiating something like: D^2= x^4 - 3x^2 -20x +104

wouldn't you need to do implicit differentiation (or follow the chain rule if you square root the distance before solving) and end up with (2D)(dD/dx)= 4x^3 - 6x - 20 and then you would need to divide by 2D and then because we know D can't be zero (because then the graph would touch the point) we just solve for the numerator 0 = 4x^3 - 6x -20 by factorizing and so on and so on.

basically I don't believe that the differentiation was able to be done properly with what we are taught for grade 12 however luckily people would still get the answer but I still feel that this doesn't follow the rules of differentiation as it should.
