Connect the ideas.
- A logarithm is an exponent; its input is positive, but its value may be negative.
- Combine logs only with valid laws and retain original domain restrictions.
- Use exact logarithmic answers before rounding a final numerical result.
- Sketch from a domain, asymptote and exact anchor points.
- Differentiate a logarithm of an input using the chain rule.
- Interpret model parameters, units and limitations; log-scale changes describe ratios.
