The Curve Sketching Series

This series discusses the strategies on graphing different functions particularly linear, quadratic, and rational functions. Curve Sketching 1 is a discussion of the four strategies in graphing linear functions. This includes two points, slope and intercept, translation, and x and y intercepts. Curve Sketching 2 is a discussion about sketching the graph of quadratic functions. […]

Curve Sketching 4: Identifying Oblique Asymptotes

In the previous post in this series, we have learned about asymptotes. horizontal asymptote and vertical asymptote. We continue this series by discussing oblique asymptotes in this post. An oblique asymptote is an asymptote that is not vertical and not horizontal. We need to know these types of asymptotes to sketch graphs especially rational functions. A […]

Curve Sketching 2: Graphing Quadratic Functions

In Curve Sketching 1, we have learned four easy ways to graph linear functions. In this post, we will learn how to sketch the parabola, the graph of quadratic functions. Quadratic Functions are functions with equation where . This is the standard form. This equation can also be expressed in the form  where is the […]
