Below are sample questions representative of the exercises included on this worksheet and related ALG2.72 Interpreting Function Parameters skill assessments:

Problem 1Difficulty: Mastery

Which statement best compares the parameter b in 400(1.2)^t and 400(0.8)^t?

AThe first model has 20% growth per period, while the second has 20% decay per period.

BIn both models, b shows 20% growth because both values are close to 1.

CThe first model has 120 units of growth each period, while the second loses 80 units each period.

DThe second model grows faster because 0.8 is smaller.

Solution & Explanation:A base greater than 1 indicates growth, while a base between 0 and 1 indicates decay. So 1.2 is 20% growth and 0.8 is 20% decay.

Problem 2Difficulty: Mastery

Which absolute value function has vertex (4, -1), opens up, and is wider than y = |x|?

Ay = 2∣x - 4∣ - 1

By = -0.5∣x - 4∣ - 1

Cy = 0.5∣x - 4∣ - 1

Dy = 0.5∣x + 4∣ - 1

Solution & Explanation:The vertex requires x - 4 and -1 outside. To open up and be wider than the parent graph, the coefficient must be positive and between 0 and 1.

Problem 3Difficulty: Mastery

Compare P(x) = -2(x - 3)² + 18 and Q(x) = -2(x + 3)² + 18. Which statement is correct?

AP has a larger maximum because its h value is positive.

BBoth functions have the same maximum value, but P reaches it at x = 3 and Q reaches it at x = -3.

CQ opens upward because the sign inside the parentheses is positive.

DThe maxima occur at the same x-value because both functions have k = 18.

Solution & Explanation:Both parabolas have the same a and k, so they open the same way and have the same maximum y-value of 18. Their h values place the maxima at x = 3 and x = -3.
