Chp 5 Exponential and Logarithmic Functions
5.1 Inverse Functions
Mirror over x=y
horizontal line test
Domain of f is range of its inverse
Create inverse by switching x and y
5.3 Logarithmic Functions and graphs
5.5 Solving Exponential and Log Functions
Solving Exponential Eq
Get same base, failing that, get same log and use power property
Step 1
Step 2
Logarithmic equations
Use log properties to get a single log term, then
convert to exp form
Solve by calc
Take each expression and graph into calc
use intersect function
5.2 Exponential Functions & Graphs
#
form: f(x) = a^x
a ≠ 1, a > 0
Compound interest formula
5.4 Properties of Log Functions
log of products
logs of power
logs quotients
subbing known logs for unknown logs
Inverse
