Basic-Point Graphs for Linear, Quadratic and Exponential Functions


The 17 graphs shown below each depict the basic points for a linear, quadratic or exponential function.  Graphs 1-5 are linear; 6-12 are quadratic and 13-17 are exponential.

You should be able to instantly sketch, with reasonable accuracy, the graph of a function if you are given its basic points and the function type (i.e., linear, quadratic, exponential).

Practice until you can do this.  You might have to refer to the solutions the first time through.  You know what you need to know for now if you can draw the graphs without reference to the solutions.  You don't have to be 100% accurate but your graph should be of the right general shape and should be recognizably close to the solution graph.

We will refine our understanding of these functions throughout the course.
