Good morning, honors algebra 1 class!

Great! Now please write this down, the set of input value for a relation is the domain whule the set of output value is the range

Great job today everyone! That’s it for today, have a great rest of your day.

A relation is a group of pairs and a function is a relation where there’s only one output

Today we are learning about functions and relations, raise your hand and tell me one thing you know about them

Yeah, functions and relations are kind of the same they both an input and an output

Well they’re different because functions can only have 1 output for every input

in a set of ordered pairs

a table or graph

an equation

Good job! Heres some mportant notes

Example of a function:

X - Y

1 - 9

4 - 8

6 - 12

6 - -9

5 - 7

8 - 4

Example of incorrect function:

x - y

1 16

17

4

-8

Raise your hand if you know one of the three ways to show a relation

A Function notation is a way to show a function related to it’s independent variable

f(x)=3x+2
