Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.11 Selecting Appropriate Function Families skill assessments:

Problem 1Difficulty: Mastery

A graph has an endpoint at x=2 and is only defined for x>=2. From (2,0) it rises while flattening out as x increases. Which function family best matches, and what feature supports your choice?

ASquare Root - has an endpoint instead of extending left forever

BSinusoidal - repeats in a regular cycle (constant period)

CRational - inverse variation pattern (y is proportional to 1/x)

DExponential - multiplies by the same factor each step

Solution & Explanation:A restricted domain starting at an endpoint and an increasing-but-flattening shape are key features of a square root function (possibly shifted right).

Problem 2Difficulty: Mastery

On a scale, x values of 1, 10, 100, and 1000 correspond to y values of 2, 4, 6, and 8. Which function family best models this relationship, and what feature supports your choice?

ALinear - constant slope

BLogarithmic - equal output changes for multiplicative input changes

CExponential - multiplies by the same factor each step

DSinusoidal - oscillates around a midline

Solution & Explanation:Multiplying x by 10 increases y by 2 each time. Constant additive change in y for multiplicative changes in x is logarithmic.

Problem 3Difficulty: Mastery

A data set has constant third differences (but not constant second differences) when x increases by 1. Which function family best fits, and what feature supports your choice?

APiecewise/Step - different rules on different intervals

BSinusoidal - has amplitude and period

CCubic - depends on the cube of the input

DLogarithmic - equal output changes for multiplicative input changes

Solution & Explanation:Constant third differences is the signature of a cubic pattern (just like constant second differences indicates quadratic).
