Finding Domain from an Equation
Domain: Remember that the domain of a function is the set of all _____________ .
When finding the domain of a function, begin by assuming that the domain is ____________________.
Then determine if there is any place where the function is not _______________, and
_______________ those values from the domain.
The 2 types of functions who have excluded values are:
1. Rational Functions because ________________________________________. To identify these
“bad” values that DO NOT belong to the domain, set the _____________________ ≠ 0 and
solve. Write your domain in _________________ notation without these excluded values.
2. EVEN root function because ________________________________________. To identify the
qualifying values that DO belong to the domain, set the expression _____________ the radical
(called the radicand) ≥ 0. Write your domain in _________________ notation.
