Unit 2B Review

The path

1. 1
   2.9 Log expressions

   You can evaluate $\log_b c$ by hand and by calculator.
2. 2
   2.10 Inverses & table tests

   You can find an inverse and tell exponential from log data.
3. 3
   2.11 Log function graphs

   You can find the asymptote, domain, range and end behavior of a log function.
4. 4
   2.12 Log rules

   You can expand, combine, and spot a log shift.
5. 5
   2.13 Solving equations

   You can solve exponential and log equations and toss fake answers.
6. 6
   2.13 Log inequalities

   You can solve a log inequality: domain first, then overlap.
7. 7
   2.14 Log models

   You can fit $y = a + b\ln x$ and solve it for $x$.
8. 8
   2.15 Semi-log plots

   You can spot exponential data and switch between $\log y = mx + B$ and $y = ab^x$.
9. 9
   Mixed practice: pick the tool

   You can tell which Unit 2B tool a problem needs.
