A level students (16-18) how good are you at graph sketching?
Firstly, do you appreciate the difference in sketching a graph and plotting points accurately and joining them up as you did in earlier years?
You could use calculus to work out the coordinates of any turning points.
(Click on the image to see this curve on the Desmos Graphing Calculator).
A graph sketch should:
- Show the correct general shape
- Indicate important features such as any intersections with the axes (on the x axis y=0 and on the y axis x=0) and where the curve changes direction (use calculus).
