Math10 Week#13

This week I learned about Domain, Range, set and interval notation. x axis is a straight line and the y axis is a vertical line.
Domain is the set of all numbers for the independent variables in the relations.
Range is the set of all numbers for the dependent variables in the relations
Function is a special relations were every input has only one output.
There is two way to solved this Equation. Mapping Notation and Function Notation.
Example:

Every time so see the an x or any letter to change it with the input.

Its the same as the mapping notation if you saw an x or any letter you change it with the input.
