Oh and listen when do we use the quadratic function, and when differentiation, to find the turning point?

Oh like x1 y1 x2 y2 formula! Could u answer my relative velocity question btw... Why can't we multiply the direction vector by the speed to find the velocity vector...why do we need the unit vector to do that?
But then dont they see the diagram wen marking coz it dapends on how people draw the tangent rytI gave 6. From tangent. I didn't realize the need to differentiate in during the exam, I differentiated it after the exam and realized it was 4.5 and I gave 6 which WILL be out of range, so 1 mark lost.

they mark according to the tangent drawn ryt?They see the tangent, its for 1 mark.
They see the answer, its for 1 mark.
No further checking.
they mark according to the tangent drawn ryt?
