Of the Graph of a Function
The following information is useful for sketching the graph of (1) The domain of , i.e. the range of values of within which is well-defined. (2) Determine whether is periodic, odd or even, so that the graph may be symmetric about the coordinate axes or about the origin. (3) Turning points and monotonicity of . (4) Inflectional points and convexity of . (5) Asymptotes including horizontal, vertical and oblique ones (if any). (6) Some special points on the graph, such as intercepts.
