Can a function’s domain and range be the same?
Yes. For example, the domain and range of the cube root function are both the set of all real numbers.
Finding domains and ranges of the toolkit functions
We will now return to our set of toolkit functions to determine the domain and range of each.
Given the formula for a function, determine the domain and range.
 Exclude from the domain any input values that result in division by zero.
 Exclude from the domain any input values that have nonreal (or undefined) number outputs.
 Use the valid input values to determine the range of the output values.
 Look at the function graph and table values to confirm the actual function behavior.
