Lesson 2: More Features
The usual features of a graph's sketch includes:
(2) Axial intercepts
Axial intercepts refer to the points where the graph cuts the x and the y axes.
(A) y intercept
It is obtained when x = 0.
(B) x intercept
It is obtained when y = 0.
Find the axial intercepts of the following equations:
(3) Stationary points
Stationary points are located when the gradient of the graph = 0.
Find the exact stationary point(s) of the graph given by
All the features (except for asymptotes) can be obtained from the graphic calculator. However the graphic calculator may not provide exact values.
