The logarithmic functio $f ( x ) = - 200 + 88 \ln x$ n x models the number of visitors (in millions) to U.S. museums from 1960 to 2010, where x is the number of years since 1960. Is this function increasing or decreasing?
A) decreasing
B) increasing

Question

Quizplus · Accepted Answer

The function is increasing because the coefficient of $\ln x$ is positive (88), meaning as $x$ (years since 1960) increases, the value of $f(x)$ (number of visitors) also increases.

The Logarithmic Functio f(x)=−200+88ln⁡xf ( x ) = - 200 + 88 \ln xf(x)=−200+88lnx
