- Today we are learning about functions and relations, raise your hand and tell me one thing you know about them
- Good morning, honors algebra 1 class!
- Yeah, functions and relations are kind of the same they both an input and an output
- A relation is a group of pairs and a function is a relation where there’s only one output
- Well they’re different because functions can only have 1 output for every input
- Raise your hand if you know one of the three ways to show a relation
- Good job! Heres some mportant notes
- Example of a function:X - Y1 - 94 - 86 - 126 - -95 - 78 - 4Example of incorrect function:x - y1 16 17 4-8
- a table or graph
- in a set of ordered pairs
- an equation
- A Function notation is a way to show a function related to it’s independent variablef(x)=3x+2
- 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.
