Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.23 Restrict Domains to Create Inverses skill assessments:

Problem 1Difficulty: Mastery

Let f(x) = √(|x|) with restricted domain x <= 0. Find f⁻¹(4).

Solution & Explanation:On x <= 0, |x| = -x, so the function is √(-x). Solve √(-x) = 4 to get -x = 16, so x = -16. That value is in the restricted domain, so f⁻¹(4) = -16.

Problem 2Difficulty: Mastery

Let f(x) = √(|x|). Choose a restricted domain that makes f invertible and includes x = -9.

Ax >= 0

Ball real numbers

C-9 <= x <= 9

Dx <= 0

Solution & Explanation:Because of |x|, the function outputs the same value for x and -x, so it is not one-to-one on all real numbers. Restricting to x <= 0 keeps only one side, removing the symmetry and making the function invertible. This restriction includes x = -9.

Problem 3Difficulty: Mastery

Let f(x) = x + |x| with restricted domain x >= 0. Find f⁻¹(18).

Solution & Explanation:On x >= 0, f(x) = 2x. Set 2x = 18 to get x = 9. The restriction ensures there is exactly one solution, so f⁻¹(18) = 9.
