In this lesson, you learned how to:
- Use technology to graph a function given in function notation, and use the graph to find the values of the function.
- Be able to identify if a graph represents a function through the vertical line test.
- Explain different ways to find the value of a function and to solve equations written in function notation.
- Explain what makes a function a linear function.
Here are the activities that helped you reach those goals:
- 4.5.1: Finding Solutions of Equations
- In this activity, you evaluated functions at a specific input value to find the output.
- 4.5.2: Using the Vertical Line Test
- In this activity, you determined which graphs were functions based on the vertical line test.
- 4.5.2: Self Check
- 4.5.2: Additional Resources
- 4.5.3: Comparing Functions
- In this activity, you compared the values of two functions representing cell phone plans. You explained the function notation in words and graphed the functions.
- 4.5.3: Self Check
- 4.5.3: Additional Resources
- 4.5.4: Using Function Notation and Graphing Technology
- In this activity, you used graphing technology to find the output value of a function given an input value. You also worked backward to find the input value given an output value of a function.
- 4.5.4: Self Check
- 4.5.4: Additional Resources
- 4.5.5: Using Graphical and Algebraic Approaches for Finding Unknowns of Linear Functions
- In this activity, you used graphical or algebraic approaches to find missing inputs or outputs. You explained the meaning of function notation in the given context.
After these activities, you completed the following practice:
