Below are sample questions representative of the exercises included on this worksheet and related ALG1.102 Domain Restrictions for Rational and Radical Expressions skill assessments:

Problem 1Difficulty: Mastery
Which expression has domain all real numbers except x = -2 and also contains an even root that adds no extra restriction?
A1/sqrt(x + 2)
Bsqrt(x2 + 4)/(x + 2)
Csqrt(x - 2)/(x + 2)
Dsqrt(x + 2)/(x + 2)
Solution & Explanation:The radicand x2 + 4 is positive for every real x, so the square root adds no restriction. The denominator x + 2 excludes only x = -2.
Problem 2Difficulty: Mastery
A family of functions has the form f(x) = sqrt(x - a)/(x - b). For a particular function, a = 6 and b = 6. What is the domain?
Ax > 6
Bx >= 6
Cx != 6 only
Dall real numbers
Solution & Explanation:Substitute a = 6 and b = 6 to get sqrt(x - 6)/(x - 6). The radical requires x >= 6, but the denominator excludes x = 6, so x > 6.
Problem 3Difficulty: Mastery
A rational-function graph has a vertical asymptote at x = -4 and an open circle at the point (2, 5). Which domain statement is correct?
Aall real x except x = -4 and x = 2
B-4 < x < 2
Call real x except x = -4 only
Dx <= -4 or x >= 2
Solution & Explanation:The vertical asymptote excludes x = -4. The open circle at (2, 5) means the function is not defined at x = 2, even though nearby x-values may be allowed.
