Graphing Functions
To represent a function graphically, calculate the points or intervals in the function where it changes its behavior. To do so, find the following mathematical characteristics:
1. Domain of the function.
2. Intersections with the x-axis and y-axis.
3. Asymptotes.
4. Increases and decreases.
5. Maxima and minima.
6. Concavity and convexity.
7. Inflection points.
