How do you find excluded values?
Summary
- Excluded values are the values of a variable that make a rational expression undefined
- The excluded values are the values for 'x' that will make the denominator, x 2 - 25, equal 0
- To find the excluded values, set the denominator equal to 0 and solve for 'x'
- In order for x 2 - 25 = 0 to be true, x 2 must be equal to 25
What are restricted values?

What are the restricted values?
The values that make the denominator equal to zero for a rational expression are known as restricted values.
How do you find the restrictions of a function?
Identify any restrictions on the input. If there is a denominator in the function's formula, set the denominator equal to zero and solve for x . If the function's formula contains an even root, set the radicand greater than or equal to 0 and then solve.
