About This Worksheet
This medium-level worksheet contains 18 problems designed for 12th Grade students practicing piecewise functions. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.
Piecewise functions model real-world phenomena that behave differently in different ranges — tax brackets, shipping rates, and signal processing are direct examples. They also introduce students to the idea of functions with different formulas on different domains, which is essential for understanding continuity at boundaries.
- Evaluate a piecewise function by determining which rule applies for a given input value
- Graph a piecewise function, correctly showing open and closed endpoints at the boundaries
- Write a piecewise function rule from a graph or a verbal description of real-world cases
- Determine whether a piecewise function is continuous at each boundary point
- Model a tax-bracket scenario using a piecewise linear function
How to Solve: Worked Example
- Read the problem carefully.
- Identify what is being asked.
- Use what you know to find the answer.
- Check your work.
