So buckle up and let’s delve into the enchanting realm of graphing piecewise defined functions!

Graphing a piecewise defined function can be both challenging and interesting. Piecewise functions are mathematical expressions that are defined differently for different intervals or sets of numbers. They often involve multiple rules or equations to describe different parts of the function.

To successfully graph a piecewise defined function, it is important to understand the rules or equations for each interval and how they relate to one another. Let’s take a closer look at the steps involved in graphing such a function.

  1. Step 1: Identify the intervals
    The first step is to identify the intervals or sets of numbers for which different rules apply. Each interval will have its own equation or rule that defines the behavior of the function within that interval.
  2. Step 2: Determine the equations
    Once you have identified the intervals, determine the equations or rules that describe the piecewise function for each interval. These equations may include various mathematical operations such as addition, subtraction, multiplication, division, exponentiation, etc.
  3. Step 3: Graph each equation
    Next, individually graph each equation on its respective interval. It can be helpful to plot several points on each segment of the graph to get a clear visual representation of how the function behaves within each interval.
  4. Step 4: Connect the segments
    After graphing each segment separately, connect them together using open circles (for discontinuities) or solid lines (for continuous functions). Pay attention to any points where two segments meet or intersect, as these may require special attention when drawing your graph.
  5. Step 5: Consider additional details
    While graphing a piecewise defined function, it’s important to consider other factors like asymptotes and special features such as symmetry and periodicity. These details can greatly enhance your understanding of how the function behaves overall.

In conclusion, graphing a piecewise defined function involves identifying intervals, determining equations for each interval, plotting points on each segment, connecting them together with appropriate notation (open circles or solid lines), and considering additional details. By following these steps, you can effectively graph a piecewise function and gain insights into its behavior within different intervals.
