Logarithms Part 1: Evaluation of Logs and Graphing Logarithmic Functions

Guided Notes

3 key concepts

  • 1

    Logarithms are the inverse operation of exponentiation.

  • 2

    The logarithmic expression log base B of X = Y is equivalent to the exponential expression B to the Y = X.

  • 3

    The domain of logarithmic functions includes only positive real numbers, because raising a base to any exponent will always produce a positive number.
