A function is just a relationship between 2 things, where one depends on the other

Domain – All possible x values

For a relationship to be a function, each input (x-value) can only have one output (y-value)

Range – All possible y values

To be a function, a relationship must pass the vertical line test

Function Notation: Introduction 1

y = 3x + 2

• Often, we use something called function notation in place of the y in equations. It is used to save time and make things simpler.

Find the value of y when x = 5

f(x) = 3x + 2

Find f(5)

Function Notation: Practice 2

f(x) = 2x+8

g(x) = 8x – 6

f(x) = 6x + 7x

Find f(3)

Find f(-5)

Find g(10)

f(x) = 2x+8

g(x) = 3x

Find f(g(5))

Bag O’ Vocab: Procedure• In just a minute, you will get into groups of 6

• You will each receive a vocabulary list for the vocab section of your binder, along with 4 yellow sheets that need to be cut

• Round 1– First team gets 1 minute, going back and forth, to describe / guess as many words as they can

• No rhymes with, no starts with, no writing

• Round 2– You must show what the word is on a whiteboard, without talking. There can be no English words written everything on the board must be math!

• Round 3– You only use TWO WORDS. You can also act it out.
