Jami Copeland. Shriya Varma. Semester Project. Straightening Relationships. In order to compare two variables using a linear regression model, the relationship between them must be linear. We know:. 2. 3. =. 8. and. 2. 4. =. 16. But, for what value of . x. does. 2. x. = 10?. To solve for an exponent, mathematicians defined . logarithms. .. Since 10 is between 8 and 16, . x. must be between 3 and 4.. f(x) = 3x – 1. 2. . 3. f(x) = 2. x. Logarithms.

Logarithms with base 10 are common logs. You do not need to write the 10 it is understood. Button on calculator for common logs. LOG. Examples: Use calculator to evaluate each log to four decimal places. The next thing we want to do is talk about some of the properties that are inherent to logarithms. Properties of Logarithms 1. log a (uv) = log a u + log a v 1. ln(uv) = ln u + e. e is a mathematical constant. . ≈ 2.71828….
