5.4 Rational Algebraic Expressions - DOMAIN
The Domain of Rational Expressions
Have you ever typed "1 / 0" into your calculator? If you have, it says: ERROR: This is because zero canNOT be the denominator of ANY expression. Therefore, we have a restriction on the values we can plug in to any rational expression. We can not have a denominator of zero.
The domain is all real numbers except those that make the denominator zero.
