Domain and Range

Domain: Set of inputs (x- value)

Range: Set of outputs (y- value)

For Example:

OR

To Graph Domain and Range:

For example Graph:

Solving Domain and Range Equation:

y= x-1

1. Make a xy-table.

2. Fill in x- values with any number.

3. Plug in the chosen x- values to the equation.

4. You then find the value of y, and plug into xy- table.

To Graph Domain and Range Equation:

y= x-1
