Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.62 Interpreting Logarithmic Scales and Linearization skill assessments:

Problem 1Difficulty: Mastery
A log-log model is log10(y) = 2.7 - 0.5log10(x). Which original-unit relationship is equivalent?
Ay*sqrt(x) is approximately 501.
By/sqrt(x) is approximately 501.
Cy*x2 is approximately 2.7.
Dy is approximately 2.7 - 0.5x.
Solution & Explanation:The model becomes y = 102.7*x^-0.5. Since 102.7 is about 501, y = 501/sqrt(x), so y*sqrt(x) is about 501.
Problem 2Difficulty: Mastery
The same original data are modeled using log10(y) versus x and then ln(y) versus x. Which statement is correct?
AThe numerical slope and intercept change with the log base, but the original-unit predictions and multiplicative conclusions are equivalent.
BChanging the log base changes the original data, so predictions cannot match.
CChanging the log base keeps the intercept fixed but changes only x-values.
DChanging the log base turns a power model into a linear additive model.
Solution & Explanation:Changing from log10 to ln rescales the transformed vertical axis. The slope and intercept numbers change, but converting back to original y gives equivalent predictions.
Problem 3Difficulty: Mastery
A model is log10(y) = 6 + 0.22x. By what factor does y change when x decreases by 3? Round to the nearest thousandth.
Solution & Explanation:A decrease of 3 in x changes log10(y) by 0.22(-3) = -0.66. The factor is 10^-0.66, about 0.218.
