5.9.7 Lesson Summary

In this lesson, you learned how to:

• Analyze a situation and determine whether it makes sense to connect the points on the graph that represents the situation.
• Describe the relationship in a graph of an exponential function using function notation.

Here are the activities that helped you reach those goals:

• 5.9.1: Evaluating Expressions for Different Values of $x$
  • In this activity, you addressed a common confusion of mistaking the expression $2^x$ for the expression $x^2$.
• 5.9.2: Analyze Underlying Relationship in a Graph of a Function 
  • In this activity, you were given a graph of a function, analyzed the underlying relationship, and described it using function notation.
  • 5.9.2: Self Check
  • 5.9.2: Additional Resources
• 5.9.3: Graph Equations to Solve Problems
  • In this activity, you graphed equations to solve problems and thought about appropriate values of their variables.
  • 5.9.3: Self Check
  • 5.9.3: Additional Resources
• 5.9.4: Deciding on Graphing Window
  • In this activity, you were given an additional opportunity to apply what you know about key characteristics of an exponential function and used it to model real-world data.
• 5.9.5: Interpret Graphs to Find Approximate Values
  • In this activity, you interpreted graphs to determine an approximate value of a function.

After these activities, you completed the following practice:
