Graphing Standards

On the next page, you will complete some questions from the Pre-Calculus 12 textbook.  Some of these questions require you to sketch a graph.  When drawing graphs in this course, make sure to follow these graphing standards:

• Plot an appropriate number of ordered pairs to ensure that the shape of non-linear functions can be determined.
  
• Label the x- and y-axes.
  
• Include an appropriate scale on the axes.
  
• Title the graph, where necessary.
  
• Define the line/curve with equation/function beside or near it.
  
• Apply arrows on the ends of the graph of the function, where necessary.
  
• Plot and label the x- and y-intercepts, if applicable.
  
• Include asymptotes, open circles for points of discontinuity, and end points, where applicable.
  
• When a graph is to be sketched, the shape of the graph is determined by important features such as asymptotes, maximum and minimum points, intercepts, etc. on an appropriate scale. All important features must be labelled.
  

Shown are examples of sketches with a grid and without a grid.  As you proceed through the course, you'll learn about other features of graphs.  Be sure to include these features in your sketches. 

Contact your teacher if you have questions about drawing graphs.
