How Do You Find Restricted Values

Set the denominator equal to zero.Solve the equation.The solution or solutions are the 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.

How do you find non permissible values of rational expressions?

Non-permissible values are values of the variable(s) that make the denominator of a rational expression equal to zero. In order to find the non-permissible values of a rational expression one has to set the denominator equal to zero and solve it for the variable.
