The document discusses logarithms and includes examples of solving logarithmic equations, graphing logarithmic functions, and properties of logarithms and the natural logarithm function. Key points covered include:
- Logarithms are used to solve for exponents.
- Common properties include loga1=0, logaa=1, and logaax=x.
- Graphs of logarithmic functions f(x)=logax have a vertical asymptote at x=0 and an x-intercept at (1,0).
- Examples demonstrate evaluating logarithmic expressions, solving equations, and using a logarithmic formula to estimate the age of an archaeological sample.
