Domain- x values, figuring out the width of the function
Range- y values, figuring out the height of the function
There are 2 different types of relations:
discrete– count
continuous– measure
Discrete is when the relation does not have a straight line and is labelled with a bunch of dots
Continuous is when the relation is labelled with a line not dots
Vocabulary:
functions
values
domain + range
graph
orgin
product
ordered pair
When writing out the domain and range, if the graph is discrete the domain and range should be listed as numbers (1,2,3,4,5). When writing out a continuous graph the domain and range will be an inequality, so the domain and range will be both the tallest or farthest point on the graph.
