Domain and Range Worksheets with Detailed Solutions

Focus on identifying the possible inputs and outputs for each given function. Start by evaluating the set of numbers that can be used as inputs and the resulting outputs based on the function’s definition.

Key step: When working through the examples, first isolate the independent variable. Determine the corresponding values by applying the function’s rule. This process will clarify any confusion about the boundaries of the function.

Tip: Pay attention to restrictions on inputs. For certain functions, there may be values that cannot be used, such as negative numbers or undefined values. Identifying these restrictions early will improve accuracy in solving problems.

For further practice, create your own examples by selecting a variety of input values and calculating the corresponding results. This exercise will strengthen your understanding of function behavior.
