# C2 Differentiation - Easy Stuff watch

1. Well this is the chapter I kinda missed at school due to illness, so Im just self teaching it all from the book and doing as many question as possible. There's just one thing - Showing that a point lies on a curve.

I may just be tired from travelling all week, but what do you do here?

Example:

With the curve y=x^2 -6x, show that the point (3,-9) lies on it.

What exactly do you have to look for here?

Thanks
2. -9=3^2 -6*3
-9=9-18

Isn't it just subbing in the values to show that it lies on the curve?
3. -9=3^2 -6*3
