2. What numbers must be excluded from the domain?
rational expression the quotient of two polynomials.
the domain of the expression the set of real numbers for which an algebraic expression is defined
Undefined domain we must exclude numbers from a that make the denominator zero.
Example
What numbers must be excluded from the domain? 2
