Math 10-Week 9

This week we learned about domain and range.  Domain is the set of all numbers for the independent variable which is x, range is the set of all numbers for the dependent variable being Y.  If you have plots across the X axis at 1,4,7 for example you would record your domain as {1,4,7}  If you had -3,6,12 across the Y axis your range would be {-3,6,12}
