Below are sample questions representative of the exercises included on this worksheet and related ALG1.110 Write Piecewise Rules from Context skill assessments:

Problem 1Difficulty: Mastery
Which explanation best describes why a piecewise model for a tax, shipping, or grading rule must include both formulas and intervals?
AThe intervals are optional because the first formula always works for every input.
BThe formulas describe what to calculate, and the intervals describe exactly when each formula applies.
CThe formulas are optional because the context words alone give every output.
DThe intervals should overlap so students can choose either formula at a boundary.
Solution & Explanation:A piecewise rule is complete only when each expression is tied to the inputs where it is valid. Intervals prevent gaps, overlaps, and boundary mistakes.
Problem 2Difficulty: Mastery
Use the bulk-discount graph. The graph shows C(n)=3n for 0<=n<=10, then a jump down so that for n>10 the cost is C(n)=25+2(n-10). Which interpretation is correct?
ABuying exactly 10 items costs $25 because the second rule starts at 10.
BThe graph must be wrong because piecewise functions cannot jump.
CBuying more than 10 items activates a bundle price of $25 for the first 10 items plus $2 for each extra item.
DBuying more than 10 items costs $3 for every item plus $2 extra.
Solution & Explanation:The first rule includes n=10, so exactly 10 items cost $30. For more than 10 items, the context can switch to a bundle price, creating a jump to $25 plus $2 per extra item.
Problem 3Difficulty: Mastery
A city pool charges $0 for ages under 3, $4 for ages 3 through 17, $7 for ages 18 through 64, and $3 for ages 65 and older. Which function P(a) models the price?
AP(a)=0 if 0<=a<=3; P(a)=4 if 365
BP(a)=3 if 0<=a<3; P(a)=7 if 3<=a<18; P(a)=4 if 18<=a<65; P(a)=0 if a>=65
CP(a)=0a if 0<=a<3; P(a)=4a if 3<=a<18; P(a)=7a if 18<=a<65; P(a)=3a if a>=65
DP(a)=0 if 0<=a<3; P(a)=4 if 3<=a<18; P(a)=7 if 18<=a<65; P(a)=3 if a>=65
Solution & Explanation:Under 3 is 0<=a<3. Ages 3 through 17 are 3<=a<18, ages 18 through 64 are 18<=a<65, and 65 or older is a>=65.
