This video tutorial covers the graphing of piecewise defined functions both manually and using a graphing calculator. It begins with an introduction to piecewise functions, explaining how they change rules based on input values. The tutorial then provides a detailed guide on graphing these functions by hand, followed by instructions on using a graphing calculator for the same purpose. Advanced techniques for graphing more complex piecewise functions are also discussed, including handling functions with multiple segments. The video concludes with practical examples and verification methods.

What is a piecewise defined function?

• A function that cannot be graphed

• A function that only uses linear equations

• A function with multiple rules depending on the input value

• A function with a single rule for all inputs

How do you determine which part of the graph to keep when graphing a piecewise function?

• Erase the part that is below the x-axis

• Keep the entire graph

• Erase the part that does not satisfy the inequality

• Keep only the part that is above the x-axis

How can you verify a piecewise function graph using a graphing calculator?

• By ignoring the inequalities

• By using only the first rule

• By drawing the graph manually
