Mathematics for IGCSE & O level - Sketching Curves (Section 1 - No. 44)
What information is useful when sketching cubic graphs? (Select all that apply)
Finding where the graph crosses the x-axis
Identifying the asymptotes
Knowing the general shape.
The turning points of the curve.
Explication
Finding where the graph crosses the x-axis is important, and knowing the general shape and turning points are also helpful. Cubic graphs do not have asymptotes.
