Chapter 11 Rational Expressions and Functions

Define an excluded value.

• Any value of a variable that result in a numerator of 0 must be excluded from the domain of that variable.

• Any value of a variable that result in a numerator of 0 must be excluded from the range of that variable.

• Any values of a variable that result in a denominator of 0 must be excluded from the domain of that variable.

• Any values of a variable that result in a denominator of 0 must be excluded from the range of that variable.

What is a Rational Expression?

• An algebraic fraction with a radical sign.

• An algebraic fraction with an equal sign and polynomials

• An algebraic fraction with a f(x).

• An algebraic fraction with a numerator and denominator that are polynomials.

What is a Rational Function?

• An equation of the form f(x) = p(x)/q(x) where p(x) and q(x) are polynomial functions and q(x) ≠ 0.

• An equation of the form f(x) = p(x)/q(x) where p(x) and q(x) are polynomial functions and p(x) ≠ 0.

• An expression of the form f(x) = p(x)/q(x) where p(x) and q(x) are polynomial expressions and q(x) ≠ 0.

• An equation of the form f(x) = p(x)/q(x) where p(x) and q(x) are polynomial functions and q(x) = 0.
