Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.7 Building Functions from Context and Data skill assessments:

Problem 1Difficulty: Mastery

Daily visitors to a site follow V(t)=5000·(1.08) to the t power, where t is days. On what day t will the visitors first exceed 10,000? (Give the smallest whole-number day.)

Solution & Explanation:Solve 5000·1.08 to the t power >10000 → 1.08 to the t power >2. Take logs: t>ln(2) divided by ln(1.08)≈9.006, so the first whole-number day exceeding 10,000 is day 10.

Problem 2Difficulty: Mastery

A delivery service charges: • $8 for the first 5 miles • plus $1.50 per mile after 5 miles Let m be the number of miles (m ≥ 0). Which piecewise function matches?

AC(m)=8+1.5m for all m

BC(m)=8 for m ≤ 5 and C(m)=1.5m for m>5

CC(m)=1.5(m−5) for m>5 and C(m)=8 for m ≤ 5

DC(m)=8 for m ≤ 5 and C(m)=8+1.5(m−5) for m>5

Solution & Explanation:For m ≤ 5 you pay 8. For m>5 you pay 8 plus 1.5 times the extra miles (m−5): C(m)=8+1.5(m−5).

Problem 3Difficulty: Mastery

A pollutant level in a river drops by 30% each day, but it cannot go below a natural background of 2 ppm. If the level is 12 ppm on day 0, which model is most reasonable?

AC(t)=2 + 10(0.7) to the t power

BC(t)=12(0.7) to the t power

CC(t)=2 + 12(0.3)t

DC(t)=10 + 2(0.7) to the t power

Solution & Explanation:Background 2 ppm is a horizontal asymptote, so use 2 plus a decaying amount. Initial excess is 12−2=10, and 30% drop means factor 0.7 each day: C(t)=2+10(0.7)^t.
