What is the definition of function?
Has inputs and outputs
Every input has only ONE output
Inputs have different outputs every time
x-values and y-values
Does this mapping diagram represent a function?
No, because an input value goes to multiple output values
Yes, because each input goes to one and only one output
Does the mapping of these points represent a function? (Note: the left oval represents your x values and the right oval represents your y values)
Function
Not a Function
