5.12.6 Lesson Summary

5.12.6 • Lesson Summary

In this lesson, you learned how to:

  • Describe the effect of changing a a and b b on a graph that represents f ( x ) = a · b x f ( x ) = a · b x .
  • Use equations and graphs to compare exponential functions.

Here are the activities that helped you reach those goals:

  • 5.12.1: Modeling Exponential Decay
    • In this activity, you practiced modeling a situation characterized by exponential decay with an equation.
  • 5.12.2: Equations and Their Graphs
    • In this activity, you examined how the numbers a a and b b influence the graph representing a function f f defined by an equation of the form f ( x ) = a · b x f ( x ) = a · b x .
    • 5.12.2: Self Check
    • 5.12.2: Additional Resources
  • 5.12.3: Graphs Representing Exponential Decay
    • In this activity, you explored how the parameter b b influences the graph of an exponential function, which prepared you to make sense of and model situations involving repeated percentage.
    • 5.12.3: Self Check
    • 5.12.3: Additional Resources
  • 5.12.4: Possible Equation for a Function on a Graph
    • In this activity, you determined the graphed equation that defined a given function.

After these activities, you completed the following practice and review:

  • 5.12.5: Practice
  • 5.12.6: Lesson Summary
