Bar and column graphs are great representations of categorical data, in which you can count the number of different categories. For this example, time is continuous in the line graph. However, it can also be categorical in the bar graphs with categories of wine.
The graph is continuous; The graph is smooth; Notice the only differences regard whether the function is increasing or decreasing, and the behavior at the left hand and right hand ends. Translations of Exponential Graphs. You can apply what you know about translations (from section 1.5) to help you sketch the graph of the exponential functions.
. . . a Line graph. Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.. . . a Pie Chart. Pie charts are best to use when you are trying to compare parts of a whole.
A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve.
Graphing. You can graph a Quadratic Equation using the Function Grapher, but to really understand what is going on, you can make the graph yourself. Read On! The Simplest Quadratic . The simplest Quadratic Equation is: f(x) = x 2. And its graph is simple too: This is the curve f(x) = x 2 It is a parabola.
