Domain of Rational

Determine the excluded values.

• x = 0

• x = 2, 6

• x = -2, -6

• x = 0, -2, -6

State the excluded (undefined) values for the given expression.

• 8, -10

• 8, 9

• -8, 10

• -8, -9

For which value is the expression undefined?

• -4

• -3

• 3

• 0

State the excluded values. x ≠ ?

• A

• B

• C

• D

• All Reals Except 0

• All Reals

• All Reals Except -3

• All Reals Except 0 and -3

What is the domain?

• All real numbers

• All real numbers except 4

• All real numbers except 2

• All real numbers except 2 and -2

What value(s) make the expression undefined?

• x = - 3 and x = 4

• x = 3 and x = - 4

• x = 3 only

• x = - 4 only

How can you find the domain of a Rational Function?

• By finding the range

  of the numerator

• By factoring the numerator and

  denominator

• By multiplying by the

  reciprocal of the denominator

• The domain is always ALL REAL

  NUMBERS

In finding the domain of the rational function \(r\left(x\right)=\frac{p\left(x\right)}{q\left(x\right)}\) where p(x) and q(x) are polynomial functions, all real numbers are allowed for x except . . .
(Check all that applies.)

• The ones that would make the function undefined.
