Presentation Transcript

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.

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.

Definition of Inverse of a Function: (composition)

Notation:

Write down what you want into “Key Concepts” as you Look & Listen.

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.
