Functions Flashcards
What isn’t a function?
when the set of coordinates have the same x-value more than twice
Function rule?
Every input (x) must have one output (y)
Domain?
Input (x-values)
range?
Output (y-values)
Ordered pairs?
The (x,y) coordinates in curly braces.
Function map?
On left oval the input is places. On right oval the output is placed. Lines connect each number.
Function table
Vertical table -x-values are always on the left and y-values are on the right
Horizontal table- x- values are always on top and y-values are on bottom.
Function graph
The X-coordinate tells us to move left/right and the y-coordinate tells us to move up/down
Vertical line test
If a vertical line going through the graph only goes through the line once, it is a function
Function machine.
Input (X-values) to Machine (equation) to output (y-values)
What is a function?
A set of coordinates that have different x-values
