  1. Work together. Use whiteboards. Use laptops. Find “f of g of x” & “g of f of x.” Form a conjecture based on your results. Opener Use the resources on the internet and each other to help you relearn the concept.

  2. 1.6 Inverse Functions SWBAT find the inverse of a function. SWBAT verify that two functions are inverses of each other. Write down the date, Section #, Title and Learning Objective(s) into your notebook.

  3. Key Concepts LISTEN LOOK Definition of Inverse of a Function: (composition) Notation: Read as “f-inverse.” Write down what you want into “Key Concepts” as you Look & Listen.

  4. Key Concepts LISTEN LOOK How to find the inverse of a function: Rewrite “f(x)” into “y.” Switch the “x” & “y.” Solve for “y.” Rewrite the “y” as “f-1(x).” Write down what you want into “Key Concepts” as you Look & Listen.

  5. How do we get there? LISTEN LOOK Find the inverse informally. SWBAT find the inverse of a function.

  6. Now let’s try together. Use whiteboards. Find the inverse informally. SWBAT find the inverse of a function.

  7. Now let’s try together. Use whiteboards. Find the inverse formally. SWBAT find the inverse of a function.

  8. How do we get there? LISTEN LOOK Find the inverse formally. SWBAT find the inverse of a function.

  9. Now let’s try together. Use whiteboards. and SWBAT verify that two functions are inverses of each other.

  10. How do we get there? LISTEN LOOK and SWBAT verify that two functions are inverses of each other.

  11. Time to practice some more by writing down examples into our notebook.
