TRANSFORMING RELATIONSHIPS
ESSENTIAL QUESTION:
How can curves be
transformed into straight
lines?
Objectives:
• To use inverse functions to transform data
into linear equations.
• To use the transformed data to create
mathematical models that will make
predictions using data.
Linear
vs.
Exponential growth
• Linear growth increases by
a fixed amount in each equal
time period.
• Exponential growth
increases by a fixed
percentage of the previous
total.
Algebraic Properties of
Logarithms
logb x = y if and only by = x
The rules for logarithms are:
1. log(AB) = log A + log B
2. log(A/B) = logA – log B
3. logXp = plog X
