Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.9 Function Composition and Interpretation skill assessments:

Problem 1Difficulty: Mastery

Let f(x)=x²−4 and g(x)=√(x−1). For which x-values is g(f(x)) defined? Select A, B, C, or D.

AAll real x such that x ≥ 1

BAll real x such that −√5 ≤ x ≤ √5

CAll real x such that x ≤ −√5 or x ≥ √5

DAll real x such that x ≤ √5

Solution & Explanation:g(f(x))=√((x²−4)−1)=√(x²−5). Require x²−5 ≥ 0, so x² ≥ 5, which means x ≤ −√5 or x ≥ √5.

Problem 2Difficulty: Mastery

Let g(x)=x+k and f(x)=x². If f(g(2))=81 and k>0, find k.

Solution & Explanation:f(g(2))=(2+k)². Set (2+k)²=81. With k>0, use 2+k=9, so k=7.

Problem 3Difficulty: Mastery

Let f(x)=√(x) and g(x)=10 − (x − 1)². What is the domain of f(g(x))? Select A, B, C, or D.

AAll real x such that x ≥ 0

BAll real x such that 1 − √10 ≤ x ≤ 1 + √10

CAll real x such that x ≤ 10

DAll real x such that x < 1 − √10 or x > 1 + √10

Solution & Explanation:f(g(x))=√(10−(x−1)²). The radicand must be ≥ 0: 10−(x−1)² ≥ 0 ⇒ (x−1)² ≤ 10 ⇒ 1−√10 ≤ x ≤ 1+√10.
