domain and range:
In week 11 we learned about domain and range. This is necessary for when a line needs to be stopped.
To start, you can picture domain as the walls. Domain uses the x axis and goes from left to right and is all the input of a function. Range can be pictured as the ceiling and floor. Range uses the y axis and goes from bottom to top and is the output of a function.
Example:
Vocabulary:
X axis: horizontal
Y axis: vertical
Domain: input values
Range: output values
