YOU DID IT!!!!

Check Understanding

Give me an a-e. • A I don’t understand at all.• B I understand a little, but not very well• C I understand pretty well, but still make lots of

mistakes• D I understand it how to do it, but couldn’t explain

or help some one very well• E I completely understand and could help a

classmate.

Objectives

Content: I can combine functions

Language: I can use the appropriate vocabulary to explain how to combine functions

Combining functions through adding

f(x)=5g(x)=10(f+g)(x)

Combining functions through adding

f(x)=xg(x)=5x(f+g)(x)

Combining functions through adding

f(x)=10x+25g(x)=8x-10(f+g)(x)

Combining functions through adding

f(x)=4x-8g(x)=3-9x(f+g)(x)

Awesome!!!!!

Combining functions through subtracting

f(x)=5g(x)=10(f-g)(x)

Combining functions through subtracting

f(x)=xg(x)=5x(f-g)(x)

Combining functions through subtracting

f(x)=4x-8g(x)=3-9x(f-g)(x)

Combining functions through subtracting

f(x)=10x+25g(x)=8x-10(f-g)(x)

Wahoo!!!!!

Evaluating Combined Functions

Evaluating Combined Functions

f(x)=4x-8g(x)=3-9x(f-g)(7)

Awesome!!!!!

Evaluating Combined Functions

f(x)=5x-8g(x)=11x+10(f g)(5)∙

Evaluating Combined Functions

f(x)= 4-10x g(x)= 7x+12(f/g)(2)

Yes!!!!

Small Groups

• If I call your name, please move yourself to the breakout room to work with me.

• The rest of you stay here and work with Mrs. Reeder on a couple more examples.

• The last 2 minutes, I will bring you all back to fill out the survey

Combining functions through adding

f(x)=3x-8g(x)=10-9x(f+g)(x)

Combining functions through subtracting

f(x)=12x+18g(x)=15x-14 (f-g)(x)

Evaluating Combined Functions

f(x)=12x-24g(x)=2x-10(f+g)(5)

Evaluating Combined Functions

f(x)=5x-10g(x)=18-9x(f-g)(8)

Evaluating Combined Functions

f(x)=6x-8g(x)=12x+10(f g)(6)∙

Evaluating Combined Functions

f(x)= 4-10x g(x)= 7x+12(f/g)(9)
