Domain Rational Expressions

• All real numbers except -2

• All real numbers

• All real numbers except 2

• All real numbers except 4

• All real numbers except -3

• All real numbers

The domain of a function is:

• The acceptable inputs for that function

• The acceptable outputs of that function

• a
• b
• c
• d

State the domain restrictions. 

• x ≠ -2

• x ≠ 2, 1

• x ≠ 2, -1

• x ≠ -2, 2, 1

Identify the domain of the following rational function.

• All real numbers

• All real numbers except x=-1

• All real numbers except x = 2 and -1

• (-∞, -4)U(-4,-2)U(-2,∞)

• (-∞, 2)U(2,4)U(4,∞)

• All real numbers

• Hint: The domain is not all Real Numbers bc there is a HOLE and a Vertical Asymptote. Find the Hole and Vertical Asymptote and exclude those values.

Find the domain for the function. f(x)= 2x -1 / 3x + 6

• x cannot equal to 2

• x cannot equal to -2

• x cannot equal to 3

• All real numbers

State the domain restrictions.

• x ≠ -3, 2

• x ≠ -1, 6

• x ≠ 3, -2

• x ≠ 1, -6
