I really dont understand how to find range of an equation of a function

Step 1

__Domain of a function__:

The domain of a function is the set of all possible values of the independent variable.

So, the domain can be calculated by identifying the value of *x* which is the independent variable.

__Range of a function__:

The range of a function is the set of all possible resulting values of the dependent variable.

So, the range can be calculated by substituting the values of *x* in the function.

Step 2

For example, consider...
