Welcome Back! I hope you had a great break! Please get seated in your assigned seat (same as the one you had with Mr. Grand) and begin reading over the syllabus.

Today Introductions Parent Letter & Syllabus Inverse Linear Functions (4-7)

Miss Jenkins From: Charleston, SC Graduated from: Clemson University Favorite Things: Clemson football, piano, the beach and food! What questions do you have?

Who are you? On your index card, please write the following: Full name – Put the name you prefer to go by in parentheses! Grade Parent/Guardian to contact Involvements (sports, chorus, band, clubs, etc.) What do I need to know about you? (seating preference, learning style, etc.)

Parent Letter & Syllabus Parent Letter – Parent Info Card (BONUS POINTS ON FIRST QUIZ IF RETURNED BY FRIDAY). Syllabus – Classroom Rules – Classroom Procedures – Honesty

Practice Please pass all information cards to the front row. Students on front row, pass information cards to the right. Student in front right corner of classroom places them in Miss Jenkins’ “Turn It In” Basket.

Inverse Linear Relations What is a relation? How do we represent relations?

Guided Notes An ____________ is the set of ordered pairs obtained by exchanging the x- coordinates with the y-coordinates of each ordered pair in a relation. Example The inverse relation of the ordered pair (5,3) is:

Guided Notes Inverse Relation Practice a.(4,-10), (7,-19), (-5,17), (-3,11) b. XY

Guided Notes Graphing the Inverse Relation Using the knowledge we’ve already gained about inverse relations, graph the inverse of f(x)=x+1.

Guided Notes Finding the inverse of a linear function: Steps: 1.Replace f(x) with y in the equation for f(x). 2.Interchange y and x in the equation 3.Solve the equation for y. 4.Replace y with f -1 (x) in the new equation.

Guided Notes

Activity Each group of three will receive a stack of index cards. Divide your cards by matching each equation with its graph, table, inverse equation, inverse graph and inverse table. Record your index card results on a piece of paper and keep for your first portfolio item!

Before you leave class… You should have: – A copy of the syllabus – A parent letter – A parent contact information sheet ( bonus points!) – Turned in your index information card – Completed your guided notes – Completed the activity and saved it for your portfolio
